Which tables to practice

A fact is included if either number is in an enabled table. Missed facts come back within 2–3 questions and are weighted more heavily in later runs.

Settings

Facts he knows fast get a shorter clock (never under 5s); missed facts get 25% more.
After a miss he sees a block array to count from (answer not shown), then types it. Missing twice reveals the last step. Off = show the full answer for a few seconds instead.
