I do it just the way Coach says: 1 1/32 down 1 inch. 31/32 down another 3/8 of an inch, no sleeve needed.
Usually go down 1 1/2 sizes, I keep the half sizes in stock. For some people, two full sizes down is too tight, your mileage may vary.
Also, I glue the grip all the way around on the bottom, this helps create the vacuum.
I use Vacu Grips myself, and we do alot of them in the shop. Growing trend. Am going to stock the lady size grips, so that we can do them for women. The smaller OD grips, have smaller sizes than the 31/32 size grips.
