I don't have any good ideas for mass dumping of dimensions, but I'm interested in the feedback of this thread. For my homebrew, I'm just going in and taking relative dimensions using a ruler for little things (distance between pops, widths of ramp/or it openings, etc) of a fully populated game. I think it'd be great if the community could come up with a list or a wiki or something that had all of that information so we could make good choices and not just eyeball things (I'm an engineer so I like precision). Obviously there will be some variability between games or even within a game, but having those numbers while going through pf design would help so much. I had to basically scrap my pf design and start from scratch because I eyeballed the orbit size and realized I made them way too tight for my target audience of the younger kids in my family. Knowing those dimensions up front will allow a designer to say "this ramp should be an easy 2.5", this should be a tough 1 3/4", etc.

Is this the kind of thing you're looking for?
