Does this sound like the set of challenges you might be facing?

• I finish all my reps of one skill before I touch the next, so when they show up jumbled together in real life I freeze
• I’ve got the basics of this down and I’m still drilling it in tidy repetitive blocks because that’s comfortable
• I can do it perfectly at my own desk in my usual setup, but the second I have to do it somewhere else
• I drill one thing until it’s smooth and then drill it some more, and it feels great in the moment
• I cram everything into one long marathon session and walk away feeling like I’ve nailed it, then a few days later it’s mostly gone

Practices that may help

1. Contextual Interference: Why Varied Practice Beats Blocked Repetition
   Contextual interference is the performance disruption that occurs when practice conditions are varied or interleaved rather than blocked. Robert Bjork and colleagues showed that despite producing lower performance during acquisition, high-contextual-interference practice (varied, interleaved) consistently produces better retention and transfer on delayed tests than low-interference blocked practice. The difficulty is the mechanism, not the obstacle.
2. Interleave practice across different skill types within a single session
   Mix practice across multiple distinct skills in a session rather than completing all repetitions of one skill before moving to another.

3. Schedule random practice for retention goals, blocked practice only for initial acquisition
   Use blocked repetition to learn a new movement or concept, then immediately shift to random practice once the basics are present.

10. Interleave retrieval across multiple topics in one session
