I sail the Viper UNI 99% of the time and quite frankly, I don't know what my mast rake is. I think it's close to the upper pintel.

I weight about 175'ish or 80kgs.

Here are my settings...

Spreader rake about 1 1/8th or about 32 mm
Tension is about 34 on the Loose gauge, the black one. I think that comes out to about 600lbs...not sure.

Sometimes I seem to go upwind with them, sometimes not. It's probably because there's a loose nut on the tiller. smile

Sorry, I can't help you much more than that.
