For having practiced Var 2 for only 12 days, I think you’re doing really well. Especially that you have also been learning the other variations also in the last month. You have made definite progress since the last recording on 5/24. There are still some baubles, but you seem to understand the basic rhythm and get it right most of the times.
If this helps as a reference point, I spent 4 months learning the 1st movement. I didn’t practice it every day but I had days of intensive practice, recording, listening, re-recording, spending 2-3 hours/day on it. This was in 2021 during Covid, but I managed to get a lesson on it which helped me deal with some of the technical challenges.
Here’s my recording from the ABF recital, if interested. I started working on the piece in mid-June, recorded this mid-August , and then kept working on it until October.
