Gilmer Drive Belt - Tension?

I posted this on Backdraft website but no response as yet:

Can you tell me what the recomended belt tension should be on the 2" Gilmer Dive Belt. Mine has never been real tight but has always provided charging via alternator. I've been reading around the net and I get a huge range from "very tight to keep it loose" but nothing specific ...

If you could give me a recomended tension (I have a belt tension gauge) or deflection measurement from alternater to waterpump on the belt I would appreciate it greatly. The alternator is still charging but belt is pretty loose and I'm concerned about jumping a tooth or worse coming off the pully. I'm sure it's too loose because I can move the belt a good 1/2" sideways (across WP pully) and the teeth on pullies are getting "shiney" from belt moving.

Thanks
