Calibrating and Streaks
Calibrating: to hone your outputs closer to the ideal (perfection/reality)
Streaks: they are momentum in perfection. streaks happen when you do perfect outputs in a row. quality can carry over and supercharges your training efforts.
example: you open monkeytype, you select your difficulty. you find a word that's difficult, you define what's the best way to "type" that word (like chords), you do that chord, you do other chords, you fail and you lose your streak (start again) or you succeed and keep your streak (keep it for as long as you can).
tldr; keep your streak. get rewarded (with momentum).
