I skimmed through the thread but didn't spot how gear ratios would be calculated in these systems, sorry if it was there, does any one know?
Its exactly the same as with a chain.
As a side note. I had no problem tensioning the belt in my track ends (not actually track ends, as the are on a 135 spaced MTN bike). I just used the standard 'walking' method. Getting the beltline dialled in is in fact easier than with a chain, too. This because the belt is stiff and can move sideways. Turning the cranks allows the belt to straighten itself. You can then easily see if the sprocket and beltring are fully engaged.
