The way you find out if the stringing is due to heat, shoot a couple of shots. Go do something for 30 minutes, come back, do the same and so on, till you get to 10.

You are assuming, and probably correctly, that the stringing is related to heat rather than shooter wearing out, which can happen after just a few shots, so you test around that issue..
