Memory is pretty secure with detache.
Played "start anywhere" game. Six measures, number 1-6. First note is C for 1st 5m-mid, high, high, low, mid (here, "high" is middle C, I2, "mid" is III4 and "low" is IVo). m6 starts with F on I. Didn't have a die handy, so randomly picked measure number to start on, or did patterns like 246135.
Found mm with fastest secure, regular 1/16 notes=68 (up from 1/8=96).
