Honest guides on click speed, input behavior and what a browser test can and cannot tell you.
Use Mouse Properties in Windows or Accessibility → Pointer Control on a Mac. Here are the exact paths, documented Windows timing values, and a separate check for unwanted extra clicks.
Jack Shi · 6 min readSpam clicking means clicking as fast as you can by hand. An auto-clicker is software or hardware that clicks for you, and servers such as Hypixel ban it. Here is the rule text, the cooldown arithmetic and what our own CPS test does with automated clicks.
Jack Shi · 7 min readButterfly clicking is commonly described as alternating two fingers on the same mouse button. Read the unverified motion, fair-test protocol, and limits of browser scores.
Jack Shi · 7 min readDrag clicking is commonly described as sliding a finger across a mouse button to produce repeated presses. Here are the unverified motion, rules to check, and limits of comparing browser scores.
Jack Shi · 7 min readJitter clicking uses muscle tension and small vibrations to repeat mouse presses. Here is how people describe it, when to stop, and how to compare browser scores without treating them as proof of technique or gameplay performance.
Jack Shi · 7 min readA higher CPS helps only when the game converts every extra click into an extra action and your accuracy holds. Here is the arithmetic for when it stops paying off, and what a browser CPS test cannot tell you.
Jack Shi · 6 min readNo fixed CPS is required for Minecraft PvP. It depends on the combat version and the server rules, and the game itself runs at 20 ticks a second. Here is what a browser CPS test can and cannot tell you.
Jack Shi · 7 min readCPM and clicks per minute are one thing, and CPS is the same rate in seconds. Changing the unit does not change how noisy a result is, but the test length does. Here is which number to track for which goal.
Jack Shi · 6 min readCPM is CPS times 60. Learn the formula both ways, a computed conversion table, why one click is worth 60 CPM in a 1 second test, and why a CPM figure from a short run is a scaled rate, not a measured minute.
Jack Shi · 6 min readA 60 or 100 second CPS result is lower than a short burst mainly because slower later seconds join the average. See the arithmetic, read the per-second chart and know what the drop cannot tell you.
Jack Shi · 7 min readA 10-second run averages a burst with the clicks that follow it, in steps of 0.10 CPS. Read the per-second chart alongside the total to see how the pace changes and compare runs fairly.
Jack Shi · 6 min readA 1-second CPS result is a burst figure, not a pace you can hold. This guide shows the arithmetic, how CPSKit counts a short run, and how to compare tests of different lengths fairly.
Jack Shi · 6 min readCPSKit does not quote a world record, because the public sources checked did not give a verifiable figure. This guide shows what a record claim must state and how to compare claims fairly.
Jack Shi · 6 min readNo test page can honestly publish the average person's click speed. Here is why, what the published research on tapping speed does and does not say, and a five-minute way to find your own typical CPS.
Jack Shi · 6 min readA good CPS depends on duration, technique, device and the rules you care about. This guide explains how CPS is counted, how to question an average CPS claim, and how to check that a high score is real.
Jack Shi · 7 min readStart from what is going wrong, or what you want to measure, and find the CPSKit tool and the guide that go with it, plus what each tool cannot tell you.
Jack Shi · 6 min readMost input faults a retailer will accept as defective show up in the first days if you look for them on purpose. Here is an ordered browser checklist for a new mouse or keyboard, what each step catches, and what it cannot.
Jack Shi · 7 min readOpen History to copy a report, print or save PDF, or export JSON. Learn what each field means, what interrupted runs exclude, and which setup notes to add yourself.
Jack Shi · 7 min readChoose one duration and setup, record five completed runs, and compare session medians. Use local History for recent results and your own log for a longer view.
Jack Shi · 7 min readThe keyboard check names the physical key you pressed — KeyA, Digit1, ShiftLeft — not the character it types. That is why it still reads right on a different layout, and why Fn and some system keys never appear. Press a key once, read the name, and compare it with the keycap.
Jack Shi · 6 min readDouble-typing is spacebar chatter; missing presses are a contact that will not close — and the space key is prone to both because it is the most-hit, off-center, stabilized key. Tap it once and at both ends in the keyboard check, watch for 2 down/2 up or a tap that never registers, and rule out key-repeat and software before blaming the switch.
Jack Shi · 7 min readA dead key sends no event; a sticky key stays down or fires on its own. Press each suspect key once in the keyboard check and read the result — no response means dead, a press that never releases means stuck — then rule out Sticky Keys and software before blaming the switch.
Jack Shi · 7 min readA key that types twice is usually switch chatter — one tap that arrives as two presses. Rule out key-repeat and software, then watch a single tap register as 2 down / 2 up in the browser, and see the honest limit of what a keyboard check can measure.
Jack Shi · 6 min readDropping mid-drag is usually the button releasing on its own while you hold it. Rule out settings and technique, confirm the premature release in the browser, and see the honest limit of what a drag test can measure.
Jack Shi · 6 min readStutter is usually software; skipped steps point at the encoder. Rule out smooth scrolling and the page first, confirm the symptom in the browser, and the honest limit of what a wheel test can see.
Jack Shi · 6 min readA wrong-way wheel is usually a software setting; jumping points at the encoder or units. How to rule out the OS setting, confirm the symptom in the browser, and the honest limit of what a wheel test can see.
Jack Shi · 6 min readThe CPS test counts left clicks only, so “right-click CPS” is not a score the tool produces. How to actually test your right and middle buttons, and why a browser cannot give them a reliable clicks-per-second rate.
Jack Shi · 5 min readPress each button on the mouse in turn and the test lights up its label — Left, Middle, Right, or Button N for extras. Here is how to check every button, what the browser actually reports for each, and what it cannot measure.
Jack Shi · 7 min readA button that stops responding is easy to pin down: press each one in the mouse test and watch which never registers. Here is how to isolate it, what a dead click can mean, and what a browser can and cannot tell you.
Jack Shi · 6 min read“It only double-clicks sometimes” is the early stage of switch chatter, not a fluke. Here is why it's intermittent, why five clicks can miss it, and how to catch it in the browser without over-claiming what a web page can measure.
Jack Shi · 6 min readA description in words rarely gets an RMA approved; a repeatable, timestamped log of doubled clicks does more. Here is how to build that evidence in the browser, export it as a report, and present it for a warranty or RMA claim.
Jack Shi · 6 min readThink your mouse is double-clicking? You can confirm it in the browser in under a minute. Here is the 60-second check, how to read the result, and what it can and can't tell you.
Jack Shi · 5 min readOne click, two clicks registered? That is switch chatter. Confirm the symptom in the browser, then try these fixes before you buy a new mouse — and know what a browser test can and can't diagnose.
Jack Shi · 6 min readA browser “polling rate test” can't read how often your mouse reports to the computer. We captured every field a pointer event gives the page — none is a rate. Here is the real list, and what that number really measures.
Jack Shi · 6 min read“DPI checker” pages promise to read your mouse's DPI in the browser. They can't. We captured every value the browser actually gives a page while the mouse moves — and none of it is DPI. Here's the real data and the reason.
Jack Shi · 6 min readOne click, two events? Before you replace the mouse, confirm what's really happening. How to separate switch chatter from the way you click — and what a browser test can honestly show.
Jack Shi · 5 min readClicks per second is a trainable rate, not a fixed talent. Here are the grips and techniques that genuinely help, the myths that don't, and how to measure progress without fooling yourself.
Jack Shi · 6 min readA larger threshold flags more intervals — and fast, deliberate clicking can trip a high one on its own. Here is the exact math, with stated example inputs you can run through the same code yourself.
Jack Shi · 5 min readDo three browsers see the same input differently? We measured it — same clicks, scrolls and keys in Chrome, Safari and Firefox on one Mac. On this setup they matched. Here is the verbatim data and the honest limitation.
Jack Shi · 6 min readAn interrupted run is a safeguard, not a failure. We triggered common interruptions across Chrome, Safari and Firefox — the browsers handled them the same way (switching tabs resolves to the same window-blur record as losing focus). Here is what each one does and why it's the honest outcome.
