25 stories is probably about right... good guess. It didn't take much time... maybe 25 minutes?
I imagine we wouldn't have faced any penalty. The few times I've been caught doing something like this I've been able to talk my way out of it. It helps that I don't damage anything.
Really I don't care about the penalties, though. I've decided to do generally whatever I want to do regardless of penalty as long as I think it's morally good.
