A local 'expert' gave my club a class earlier where he said that if a paph is staked too early the bud will still droop to try to adopt the posture where the dorsal sepal shields the pouch. I think in the wild, that way the pouch/pollen is shielded from rain. He advised that the bloom should be allowed to 'harden' in the drooping posture, and then staked up. This is supposed to help it retain a better display appearance.
I am not an expert, just passing along info.
