I agree totally Andreas.
I’ve just given up caring. Zwift racing is fun and great training. However, it has little or no bearing on actual ability. Cheating is incredibly easy. A surprising percentage of people do it. Those that think only a small percentage cheat are living in a dream world.
To get even near to fair racing, every racer on Zwift would need actual accurate scales, accurate weigh in protocols, accurate height protocols, multiple high quality power sources and a team of people going over that data for every single event. Obviously, that’s impossible, so it’s the wild west.
Current power meters are all over the show re accuracy, even from single brands. How these are all supposed to be level from multiple manufactures. No chance.
Currently, we’re supposed to use the least accurate power meter available to us, the low quality trainer, to control the game. A friend of mine is a cycling coach, he sees tons of power data, daily. His real world experience… the chances of having equal and accurate data from all of those different sources… zero. Absolutely zero.
Then, add in two little boxes where we can just write in our ‘numbers’… I’ll be 50kgs and 140cm thanks 
So, if an independent tester arrived at our home, weighed us pre race, installed an accurate calibrated power meter before every race and oversaw the upload of that data. Maybe then, it would be close to real. Maybe…
Until then, it’s just a game, a fun social racing platform.
It’s not real. Not even close. There’s a metric truckload of cheats.
However, the pen enforcement is good start. You’re 100% right, it won’t stop determined sandbaggers, cruisers and rampant cheats.
It’s just a start, I think we’ll all agree that anything is better than nothing at this point.
