Closed vs open back can make quite a difference. There are so many, many factors at work that I wouldn't even try to figure it all out. I think that the venue is the biggest unknown. Even a door being open or closed can have a minor effect on how much sound is bouncing back to your guitar and the size of the crowd has a very noticeable effect.
Then there's playing out of doors. That's a whole 'nother world.
