My parents had a Nordic Trac I used when I was in college, and I bought one last year to work out on. Well, I’ve pulled it out and started using it; however, an old question has surfaced in my mind again:
What in the world is “Perf Index” on the Achiever BC-887 for?
It can’t be calories because it doesn’t know how much resistance I have. The only connection is speed and time
It seems to count linearly so that at 12km/hr, I’ll hit 100 in 20 min covering 5km.
Oh well, any ideas out there?
By the way, the image is from a google cache of an old expired ebay auction. One of the few I could find.
