The wing starts to work immediately. Just not much. This is a pedantic but important point. Even low speed motoring events aero can be very very important if sufficiently large wings are allowed. Aerodynamic gear for cyclists is advantageous even if you are a slow cyclist, etc.

Popular "wisdom" in cycling is that aerodynamics are not a factor below 10 mph and not much of one at 15. It becomes pretty noticeable in the 15-20+ mph range (increasing with the cube of speed, or something like that).

Yes, but the physics is that the amount time saved over a fixed distance is actually more for the 15mph cyclist than the 20mph cyclist.
However the percent of time saved for the slower cyclist is less, but only a little.
Basically at cycling speeds the aerodynamic curve is pretty flat so it doesn't really matter if you are fast or slow.
