Above ~500 wpm comprehension degrades — you're skimming, not reading (Rayner et al. 2016).

Font preference doesn't predict your fastest font (Wallace et al. 2022) — this measures it instead of asking you to guess. Rough single-run estimate, not a clinical measurement.
This tests each of your 8 fonts: text starts at 250 wpm and deliberately speeds up until it's too fast to follow. Press space (or tap the display) the moment you lose the thread — that marks your limit for that font. Repeats for all 8, about 3 minutes total. Speed is capped and each font times out on its own, so it can't run away — and Stop (or Esc) quits anytime.
