There is no doubt the more diverse, undesirable and unexpected conditions we train in the better prepared we will be.
Not to derail this thread but how about not securing all four corners of a paper target? the wind may blow up/down an edge and partially reduce or obscure your target. I have seen people hesitate with just a corner flapping a little bit, even though the intended POI was fully visible. The little things that people don't expect to happen seem to have a major impact on their actions/reactions.
It also interesting how shooting an unfamiliar drill/scenario effects performance.
