If you had a razor that was shave-ready but due to use has become dull enough not to be able to shave comfortably, how much honing would you do to get it back into shape?

I know there are lots of variables, but give me your gut instincts. If the razor is carbon steel and you only have a Norton 4k/8k to work with (along with the final polish on a Tony Miller 2.5" honey brown strop), how big of a pyramid would you do? I was thinking of doing a 3/3 1/3 1/3(5) and then testing with HHT...sound good? Or is there another suggestion that doesn't involve doing a pyramid?

Any help would be much appreciated.
