The problem is that w/kg is here for now so that will be used rather than categories, but you could at least put cones on the cheaters.
They’re still trying to figure out how to do that well.
I had saw a comical situation in a B race where a Zwift developer I know who’s absolutely a legit B got cone-of-shamed halfway through the race. He wasn’t happy.
That’s funny 
But that’s why the cone is in Beta so they can fine tune it. I really wish they would start administering the ZHQ Anti-sandbagging green cones in more races! This technology was released in early April, it’s a half a year later! C’mon Zwift HQ throw us a bone and start expanding the races and series that use this technology!!
There are a number of admittedly good reasons why it hasn’t been rolled out more broadly. I actually wrote the code that does the “green cone.” But there are some significant limitations with it which is why it hasn’t been rolled out more broadly. I originally built it as an interim step to a larger system that was shelved; so now we’re doing the work to figure out what needs to be done to actually make this a more complete feature.
