Just count it so that your players are on 99% for the next match.

If you have a match in just over 3 hours, you'll want to train your players to 94% so that they hit 99% after the next 5% gain.
If it's a tough match, don't go below 94%.
If you're quite confident, train them to just below 94% so you don't waste any of the 5% gain.
