Interesting comparison Moose.
I feel like over-gripping isn't my problem, I can feel the forearm is acting differently to 'usually' (i.e. when I haven't just had two months of ancap training on steep board and lattice), it's producing more lactic.
My understanding is I'm increasing my ancap from session number 1. The adaptation time to full potential is an average for 'geneticly average climber x' to reach full potential, but the potential increases over time rather than suddenly start adapting after 'week x'.
Not a bad 'problem' to have really as I'm strong(ish) and now have good strength-endurance over 10-15 hard moves, and the solution seems to be just continue with lots of nice aerocapping territory aka 'trad' and aero finishers indoors following ancap sesh's.
Also I'm over trying to peak for routes Ally!.. after two years of experimenting I've come to the conclusion it simply doesn't work well in the UK to go through a 12-16 week periodised build-up to give yourself a 4 to 6-week golden window of beastliness; during which weather, partners, route conditions and work pressures all impinge on opportunities to make full use of the momentarily increased performance. For me the sacrifice and demotivating effect of missing out doing other good stuff isn't worth the payoff.
So I'm following a general periodised training plan but with a view to long-term gains, not annual peaks, while still fitting in all the other stuff I like doing - trad climbing, ice climbing, bouldering, mixed climbing, dry-tooling, alpine, that might not be optimal training for my goal routes. Will still be trying Mecca this autumn but I won't be trying too hard to time things just right/taper/stress over the length of a peak period etc.
For a foreign trip to tick a specific route or routes I think periodising/sacrificing other climbing is probably worth it.
