generally, when a horse changes owners, I like to give them at least a couple days to settle in. I see it as a sort of courtesy to the horse, who has suddenly been removed from its home, buddies, owners and tack, and it now in an entirely new situation. I know if I swapped places I would hope for the same courtesy.
some horses need much longer than a couple days as well. My BO purchased a 10 year old gelding that was well broke, but had one owner his whole life, and hadn't traveled much. He had a really hard time adjusting, and went from a nice quiet gelding to spooky, touchy, flighty mess. It took a full month and he was back to the same horse he was when purchased.
Also, I don't think shows count. The horse knows its rider and tack, and after a few shows, knows the routine, unlike a horse that has just changed owners/locations.
