that would also be waaaaaaaay too fast (20 fps).

manufacturers will provide documentation to easily calculate the kinds of loads their products can handle.

Math, it's great stuff (the calculation for speed is also a quick one).

We were geared for 23 fps in 2008, but that game was suited for nearly-out-of-control speed.

Well I do know that Chris did upload a great white page about belts vs chains. Take a look at that for more information as well. They found that 15 mm belt is a bit better structure wise than chains but the area it takes up may limit a few things.
