I could read that the rider in the front group who made a huge break with lower w/kg was riding 454 wheels, most of the others where on tronbike, so that wheels set was way quicker than tronbike, there must be other wheels to, there must be a list, or then zwift insider maybe know what they should test next:) just the jungle time he made a 1,5 min break from a group hammering higher watt/kg numbers out. On twitch m_nim was streaming there you can see what was going on if you are interested;-)
