SpeedWait for the flash, tap. Five taps, average milliseconds, a tier from LIGHTNING to PING 999. Sleep and caffeine move this number.
The Performance Lab
The arcade next door plays cartoons. This room measures you. Three instruments with real pedigrees, thirty-second protocols, and a tier ladder built for the group chat. Your numbers stay on your device — beat them tomorrow.
Recall
MemoryThe grid lights a pattern, you tap it back, every round adds one. Your span lands you on the animal ladder — goldfish to mainframe.
Track
Precision25 archery boards, every tap scored by ring — bullseye is 10, grouping is everything. No misses, just worse arrows. 250 on offer.
On the bench
In the pipelineVigil (three minutes of pure focus), Switch (the rule keeps flipping), Steady (the buzz wire), Wide Angle (edge-of-eye catches) and Breathe (the calm one). The blueprint is written; the bench clears in order.
Lab numbers are honest but homemade: your screen, your hardware and your thumbs are all in the measurement, so the fairest fight is against your own best on the same device. The tiers are banter. What genuinely moves these numbers is no mystery — start with the sleep calculator and the caffeine calculator, every formula cited.
