OP asked no such thing. OP asked how not to get dropped in Zwift.

As we used to say, “All models are wrong, but some are useful.” If you’re going to ride or race in Zwift you have to know or understand the differences between real life and the simulation as it relates to your riding. More important ‘unrealism’ than the ‘power-ups’, I feel, is how Zwift treats drafting, how certain bikes can draft and some cannot, and how the artificial ‘braking’ it applies downhill differs in races versus solo rides.

All cycling races, in virtual world or real world, are unrealistic because they’re all games with their own ‘unrealistic’ rules. But that something is unrealistic is not automatically material or significant to the competitors as along as all the rules are applied equally.
