decent, but I imagine we'll see 9R, at least. had fun with both metrics, didn't quite get through programming my cost layout though. 
Input chamber was a bit useless. I considered trying to drop to silver->lead instead of gold->tin just to use some space, but it wasn't really necessary.
output chamber is actually one of the more cramped ones we've had in a tourney puzzle, from what I remember. neat to have something different.
