After a couple of weeks in Zwift I think I’ve mostly calibrated myself to slipping into a draft but I think this is a point where the game needs to break from reality a bit. It’s really difficult to drop the EXACT amount of watts required to trim your speed, tuck in, then not jump back out into the front or off the back.
Today I was riding on the flats at about 200 watts and to join a group coming up from behind I had to VERY GRADUALLY start trimming watts when the group reached around 17m and closing, then level off at exactly 168 watts to tuck in, then remain within 10 watts +/- to retain position. This is like connecting to the international space station!
It might be worth exploring giving riders in the slipstream a larger wattage spread where their avatar maintains position. Since we don’t have the same tactile input that we do on the road this will greatly enhance group riding.
Along with that leeway one would, of course, have to spike their wattage a bit higher to “break free” of the draft to take a pull. I don’t see this as a problem–on the road once you pull aside you’ll be blasted by the wind anyway, resulting in the required spike in effort.
