Started cubing again at around September, I was averaging about 1min 30, in about 2 months I became sub 30 and it feels like I just stay there.
As much as I practice it feels like it's not making me any faster, I been stuck at between 25-30 over the past month, last month I did an AO100 and got 26 ish, now my average is around 27-28 and I've practised more than 100 hours. What am I doing wrong? I'm solving it over and over. My aim is sub 20. Please help with tips and how I should practice.
