My luck is usually best the first time in a stand. But I think some of it has to do with the fact that I wait until what I consider to be the "best" time to hunt it. Not just wind conditions, but wait for a cold front to come in, waiting until the bucks are starting to chase etc. I killed my buck on the 3rd time in the stand this year, saw a nice one out of it the second time. I've only hunted the stand 5 times this year total.
