as everyone, i usually experience a certain grade gap between my usual "quick sends" and the hadest i can boulder (or redpoint) after many tries spread over several sessions. Nothing weird.
Now, in the short period (weeks-months) i've experienced times where the difference seemed to be narrower than usual (ie i tend to be more consistent and feel more comfortable than usual on easier grades but don't seem to make progress on any "big project") and times where it seemed to be greater (a few amazing isolated sends, compared to my "average" level)
I don't think it's simply a matter of how i manage my attempts over a day, but can't come up with very convincing reasons for the two "anomalies".
Does anyone here have possible explanations, especially training-related ones?
