The three C2 model C's at my gym are equipped with PM3 monitors and are all giving a max drag reading of about 80. Maybe they just need to be cleaned, but it doesn't "feel" like a df of 80 either. The ergs just feel slow, and in fact my efforts don't seem to be rewarded like they usually are.
Could all this be resolved by vacuuming the vents, or do I need to check if the PM3 is in fact set for a model C? I thought that dirty vents could explain a low df, but not an inaccurate df.
