Tired vs Fresh Reaction Time
Compare tired and fresh with the same short set and device; if the spread widens when you’re wiped, rest or stop—don’t grind for one lucky click.
A lights-out score can look worse after a long day, and the gap between the fastest and slowest clean taps can get wider. That is a practice note on this drill. It is not a health check. If the taps no longer agree, stop the set.
Compare a tired session and a fresh session the same way. Same device. Same short length. Same rule for early taps: leave them out. Then read the spread, not one lucky click.
Compare on the same device and a short set
Fair means the only thing that changed is when you ran the set. Keep the screen, the input, and the length the same. A new phone or a new keyboard is a new clock, so a jump after you switch devices is a setup change.
- Same device. Score both sets on the phone, keyboard, or panel you will actually use. Do not mix a tired set from one screen with a fresh set from another.
- Short sets. A handful of clean lights-out taps is enough. Add tries only while the taps still cluster. A long grind mostly records taps after the cue went fuzzy.
- The spread. Slowest clean tap minus fastest clean tap. If that gap is wider when you are wiped, the set is done. Rest or stop. Do not keep clicking for one personal best.
How to read the average of the clean taps and the spread — not one best click — is in how to read your reaction time score. What to watch when those taps stay far apart is in reaction time consistency: what matters.
Run the pre-race set when you are fresh
A short scored set before a sim session is a check, not a full training day. Do that check when the taps still sit close together. If you are already wiped, that set will not tell you much about the race you are about to run.
How many tries, what to ignore, and when to stop before you race is in short reaction drills before racing.
Stop when the spread blows up
If the clean taps start to wander, the set has stopped agreeing with itself. Rest or stop. A wider spread is a reason to leave the drill, not a reason to hunt for one fast tap.
What to change when a short set has flattened is in reaction time plateau: what to change. How a few clean reps lead into a scored set is in reaction time warm-up and progress. Save the longer plan for a day when the taps still cluster.
