Which makes me wonder if you can apply this as an autodidact. If you know you have made subtle changes, do the results still hold. I'd guess the answer would be yes but it could be an interesting problem.
There also might be a delta (variation of the activity) that optimizes the learning progress. My guess for that would be...change too little and you're inefficient, change too much and you are inefficient, too.
