Murmie,

It really depends a lot on the amount of spine wear, which dictates how much metal you're having to remove. The wider the bevel, the more time on the hone to get the bevel.

I have a couple that have significant spine wear to the point of being near wedges. On those I've used up to 4 layers of tape, usually one layer too much, but that's what it took to basically recreate a spine to correct the geometry and give a narrower bevel.

Depending on your razors wear, you could start with two, or none and just see what it's giving you and adjust the tape accordingly. If you don't go overboard with the test edge, it doesn't take much to hone it out.
