Observations that remain valid
A worthwhile retention delay finding appears on a defined task under conditions recorded for drift episode, not merely in accumulated sessions. Follow-up may adjust the routine when both retention delay and drift episode remain manageable.
A neutral present anchor result is useful too. When redirection cue remains unchanged amid frustration or poor fit, the product may not earn further time or data.
What redirection cue still cannot answer
Practice effects, changing cues, sleep, and stress can alter drift episode; familiarity and assistance can also reshape retention delay. Neither the drift episode nor retention delay record separates every cause, so this conclusion stays task-specific.
A concerning change beside redirection cue should pause self-training. Seek suitable help when the associated present anchor pattern is sudden, worsening, severe, or unsafe.
