I get your dilemma, however, I think you’re in the far minority. IMHO, there are very few people with a 5.5 FTP. That is pro level power. So to have pro level power, and not have a power meter, or be running a HRM… I eye that with extreme suspicion. Sorry. Not calling you a liar at all, I just mean in general in the game.
You know how many times I have power-meter riders pass me, holding over 4.5wkg for anything over several minutes? Very, very few. In races, sure, they lead the pack. You know how many zPower riders pass me doing 5 wkg+ ALL THE TIME, literally every ride. It’s a problem. Last week a zPower rider passed me doing 25 wkg. He was going so fast I literally couldn’t flag him, because he was gone by the time I could get the rider list to refresh in the Companion app.
And yesterday during one of the Zwift Classics rider (30 miler), I was riding with 4 zPower riders in one small group, all putting out 4+ wkg. One them, put out 4.5-4.8 for a solid 20 miles and dropped the group, no rest, no fluctuation (I was following him). I couldn’t hang. And yes, there are riders IRL that can do that, but with zPower riders, you can tell it’s just not accurate. They rarely have heart rate data to back it up, and they rarely take rests or vary their power by more than 0.5wkg. That tells me they’re just probably tempo riding IRL.
You call us bleeding hearts, I say if you want to be faster than 98% of riders on there… prove it. Or just ride or do workouts on your own, or do another service that isn’t focused so heavily on group riding (which it seems like you have). A big part of the appeal of Zwift is the group dynamic and riding with others.
IRL, this would be like doing races where eBikes were mixed with regular bikes. Having tried to race an eBike rider up a gravel hill once… I can assure you it’s a discouraging, and losing, battle.
