That sounds like a solid plan. We could map the intervals, look for repeating motifs, and use simple statistics to see which parts get stuck in your head. From there we can build a routine that targets those patterns, gives you enough repetition, and keeps the practice balanced. I can help sketch out the math—just let me know what data you have.

First write each note of a passage as a number (C = 0, C♯ = 1, …, B = 11). Then subtract successive numbers, adding 12 if the result is negative, to get the interval in semitones. List each interval in the order it occurs. Count how many times each value shows up—C‑major third is 4, perfect fifth is 7, etc. Once you have those counts, you can make a bar chart: on the x‑axis put the interval (0–11) and on the y‑axis put how many times it appears. If you’re using a spreadsheet, just feed the list into a histogram function. The peaks will tell you which intervals you’re repeating most, so you can focus your practice on those or on the ones you want to introduce more often. That should give you a clear map of your patterns.

Sounds like a solid plan. Once you have those peaks, just slot in targeted drills for the heavy‑hit intervals and sprinkle in fresh ones where you want variety. Let me know how it turns out—happy to fine‑tune the approach if anything feels off. Good luck!
