Bore cleaning - how often / how much?

When I am working up a few different loads for my 270 win or 30-06, how many shots should I fire before cleaning the bore and starting over again? I have been starting with a clean bore and one fouling shot before shooting groups of three with small increments of powder for each group. Ideally I see a group that hits the "sweet spot" somewhere in there and later load to replicate that round. Typically I shoot about 6 to 8 groups of three. After each testing (18 to 24 rounds) I clean the bore with Hoppes #9 and/or Hoppes Copper Killer and brass or nylon brush until the patches come out clean. Then I begin the cycle again with one fouler and the next load with 18 to 24 rounds. Does this cleaning regimen make sense to you more experienced shooters? Is one fouler enough? Do I even need to clean between each developmental cycle of 18 to 24 rounds? I don't want to clean excessively often or not enough. Thanks!
