Looking at my Strava VAM values from a century I rode in the Santa Monica mountains last Sat. - they're really all over the place!
The lowest is 607 but the highest is 3,076 . . . which should be impossible, certainly for me. For the poll I went with 610-762 since that seemed to represent the most often seen values on my Strava. Here's a link if you want to see what I mean (and see if you think I voted correctly):

Not that I claim to totally understand VAM, though I do appreciate the education by Hermes!
