Pure simple reaction time (SRT). Pros sit around 180–200 ms. Caffeine, sleep, and warm-up move this 30–50 ms.
Hick's law: with four options you should land roughly 1.5× your SRT. Below 400 ms is junior-pro tier.
Go/no-go fires the same loop as taking a penalty: stop a motor program you've already started. The 25% no-go trials are the ones that matter.
Wide-field perception. Top scouts test elite skaters here — their eyes scan twice as fast as average juniors before puck contact.
First 2–3 attempts are warm-up. Run the set twice before logging — the second number is your actual.
Don't hunt the corners. Lock the crosshair, let the periphery come to you. Same scan you use on a 2-on-1.
Left index on Q/A · right index on E/D. Both shoulders relaxed. If your wrist is tense, your RT is 40ms slower.
Reaction is metabolic — the cortex needs glucose. Sip water, breathe through your nose, then go again.
