I put this together by mashing up some of the stuff that John's posted here plus the skyrunner calculator. If you follow the link, you'll get to an excel online sheet. You may have to click "edit in browser" to open it up. Thereafter, select the Enter Time sheet, put in an ascent goal time, and then select the Bracelet sheet, and you should have a reasonably formatted bracelet with landmarks, grades, and some associated accumulated times for those landmarks. Wrap it in packing tape and you can sweat all over it. At least that's my plan.
