Hard to be definitive - the last two weeks needed 3 ingredients; frequency, extra protein, and proper rest. I think you probably got 2/3. It’s difficult to predict if you’d gotten 8hrs a night, and maybe extra daily calories with higher protein intake, whether you’d have achieved better performance results. You should have but it’s unrealistic to say in absolute faith that you would.
However what you can safely conclude is that if you don’t get the balance between all 3 right then you’ll definitely get suboptimal performance.
I think cycling intensity and increasing volume might be the better way forward for you on press ups - I’ll give it some more thought and come back with some suggestions.
