I do this, too, but only with enough air for the tube to resemble a slightly-limp donut. That way, it's not placing any shear stress on the patch. With how lazy I am, it might be a week or longer before I take the tube off the peg and deflate it for storage. If it still feels about the same after that time, I feel pretty good about the patch job.
