Anything less than 87° one better be very precise with their edge control.
Having been to Toko Wax & Tune clinic and picking the brains of many throughout the years I wrote an article on this. It's on bob's ski page at lacyslatherworks.com
you can print it out but it will turn out 10 pages when it is supposed to be only about 3 pages. My wife double spaced the darn thing because she couldn't get the margins right and keep the paragraphs right. We only have Front Page ver 4... an oldie, and we don't know nuttin' about html.

and I'll send it to you. There are many good waxing procedures. This one has earned me many smiles and praises when people come to pick up their skis after a wax and tune.
In short, when done, you should not be able to see any wax on the bases. The wax belongs inside the base, not on top of it. Wax needs to be out of the structure of the base. Structure is those little lines in the base you can feel with your finger nail when dragged sideways across the ski.
Basic rule of thumb: SKI 2 DAYS, WAX! Yuo can't wax too often!
Tune twice a year unless you notice the edges getting dull sooner. btw- most skis come from the factory at 1° & 1°, give or take a bit. it seems to average out to about 1&1. Anything different from that is according to personal preferences. Bob
