Look for trend, not display
A fast outlier is less useful than several controlled runs that describe the student’s real baseline.
A single strong run can be misleading. Practice history is more useful when it shows whether a student can repeat the same technical task calmly across days, tempos, and sessions without the result drifting.
A fast outlier is less useful than several controlled runs that describe the student’s real baseline.
Use the same exercise, tempo range, and assignment frame before deciding whether a week produced real progress.
If tempo changes, keep the rest of the assignment stable enough that the next decision remains clear.
Confirm that the student practiced the intended exercise, hand pattern, and tempo target rather than a looser substitute.
Look for repeated, comparable sessions that hold together instead of isolated best-case attempts.
Either keep refining the same tempo or raise it modestly, but avoid changing multiple technical demands at once.
