has anyone compared there ftp test with a newton and a direct force power meter? are they close??
Something would be pretty wrong for that not to be the case because the differences between units would tend to average out over a 20+ minute test.
A few watts difference would be normal however - just as you'd likely see a difference between any two DFPM units.
