The biggest issue I noticed is that it seems to miscalculate speed in some instances. For example, I’'ll be climbing the hill with a few folks all together. Then after we crest the hill, one or 2 people at say 2.5 w/kg move ahead by 1m - 2m even though I’m at 3.2 w/kg. I keep my pace going but can’t seem to catch back up unless I kick it up to 4+ w/kg.
I’m on a computrainer, and I’ve observed this even with one of my buddies who is also on a computrainer. I’ve also done 10 laps with someone (not sure what trainer they were on) where this NEVER happened even once.
My only guess is that it’s somehow overstating the impact of weight when going downhill. I’m pretty light (138 lbs), so I’m thinking maybe it makes me put out a ton more wattage to stay with heavier folks going down hill. Still 3.5 w/kg and still get dropped by folks doing 2.5? That seems way off.
