In terms of on-demand performance, I think that recency will trump about everything else. The last time that you confirmed your kinesthetic alignment of the gun via dry practice or live fire and the ability to execute the basic motor programs needed to run the gun will be hugely important.
If I'm worried about on-demand performance, I'd make sure I was dry firing as much as possible. I've found that I can deliver most of my performance potential with 4 sessions of dry practice and a 100 round session every week.
Jeff Cooper recommended presenting the gun 10 times before you left the house. If you do this, you're about as prepared as you can reasonably be.
