I don't have the complete answer to your question, but here's one very important thing I would do:
First, shoot like you would do normally. For me, that means shooting with blow-tubing, like I would do in a match.
Then when you've finished your string of fire, get a dry patch ready to go on a cleaning rod. Blow tube again (using the same number of breaths as you would normally do between shots) and then immediately run the dry patch down the barrel, paying attention to how smoothly the patch goes down. Take a close look at the patch for a) streaks of lead, and b) note how dry the fouling is.
A smooth path down the bore, no leading, and moist fouling on the patch, are things you want to see.
