Power and single-move technique seem don't seem to be the issue just now: in the summer before I injured my finger I was doing font 6A problems (indoors) onsight or in a handful of goes, but I'm not routinely onsighting F6a yet. I generally find the moves easy on the routes I'm trying: what stops me is getting pumped and/or scared.
this alone makes me think about
-as many moves as you can during your session, so medium intensity and very small rests :as soon as you are fully warmed up, aim for a medium pump. Do not recover 100% and try something at your limit, get on the holds when you feel 70-80% "fresh". Link 3-4 boulder problems with very small rest : climb, jump off, climb again.
then you have a recovering pulley injury, so you'd better focus on technique drills (that match well with medium intensity-high volume work)
-focus as much as possible on execution quality, that means : fast, dynamic AND accurate at time. You should not be climbing slowly and static all the time, you should not be pulling so brutally that you start messing up your footwork. Work a lot on finding the happy medium.
-use the momentum from the previous move. Eg, if you have to cut feet lose, aim for the perfect foot placement on the swing back in, do not allow you a second swing. Same for every side oscillation/twisting, see if allowing a bit of it can make the start of the next move easier.
-do not readjust your hands on the holds, unless it is a major readjustment during a complex move. But generally speaking, the way you grab it, you pull it (immediately, no dead time on holds). Aim to get holds "right" the first time.
-If it doesn't make things significantly harder, choose beta where climb on 1 foothold and use the other leg for balance. Even better if you can link several hand moves without moving your feet (example: 2:32 @
4 hand moves with the same right foothold, quick qnd effective)
