I've seen interleaving research like this before and it's my understanding interleaving trains not just the ability to work a particular problem but the ability to better recognize the class of problem. Anecdotally, after reading a paper on this, I made a Python script to drill guitar pieces, chords, progressions, etc. in an interleaved fashion and I believe it has helped me become a better player. Before doing this, when I would practice, e.g., scales, I might start in A then B, C, etc. but what I noticed was after doing the first scale, the rest were just minor variations so my training went from deliberate to auto-pilot. Now, with interleaving, I have to give some brief thought not just to how to mechanically perform the piece but what exactly the piece being asked for is. Consequently, during a performance, my ability to go from an intention of doing something on the guitar to actually plucking the first string is much more comfortable and faster.
