I’d just try to not stress too much about if you can get better progress doing something else, that’s always a tough hole to climb out of. There’s obviously no reason to say you can’t ever make a change, but better to just keep plugging away while you can. If you are making progress, even if slow don’t work yourself up over change, steady progress over a year is better than lots of ups and downs and changes and maybe not seeing why.
If you have to think about training focus on understanding better what you are doing and how to look at it. Improve how accurate your rpe/fir is, learn to see what areas you are less “honest” with yourself about in training, what you do well, etc. Look at how it’s progressing and learning what you seem to respond to, etc.
Not saying not to ever wonder about changes, but also once you move past looking at “programs” or “plans” and understanding what underlying principles are driving your progress it’ll make it easier to not constantly be wondering if you should be doing something else.
