I had a reading of 250Lbs on the belt when the Spyder was new.
Now that I have 2500 mi on it, it reads 220Lbs. I've never adjusted it.
That will give you an objective point to start from in adjusting the belt.

You should be able to go lower that that if you like, there's quite a bit of wrap on the belt so slipping shouldn't be a problem.
Thanks for the info Latemarch. I'll keep the Gates gauge in mind if needed. I did loosen the belt some more since my last post and it made a BIG difference this time. The sound it still there, but it's very minor and no longer embarassing or annoying. If it stays like this or better, I'll be content. I think I could probably go a bit more if desired. My belt is still snug with no slop, but I can now move it a bit where before it was so tight, it didn't move at all. I put over 400 miles on it since this adjustment and in addition to the improvement in the whining noise, the bike just "feels" better. Maybe it's my imagintaion, but it just feels like it rolls more freely, even when pushing it around in the garage or sitting on an incline at a light.

I'm obviously not the only one with this issue, so I hope this info can help someone else.
