Oh FFS. I get that. But incessant whining on the forum about motos in front, motos behind every group, now people are gonna complain about motos behind?
Motos and cars behind ARE er problem, because they push a cushion of air in front of them - but they need to be closer to have effect than when they are in front.

The wind shadow in front works for 50-70m, the cushion behind for 10-15m.

I'd hoped there was nothing in my comments that suggests I don't understand that.

Remco better attack from behind when Skjelmose’s turn on the front is about the end. Make him work to get back to you. Don’t think he drops the Dane uphill today.

Using computer simulations and wind tunnel measurements with scale models of a time trialist and a motorcyclist, the researchers calculated that a motorcycle riding at a short distance (0.25 meters) behind a cyclist reduces their air resistance by nearly 9 percent. With three motorcycles, this reduction even reaches approximately 14 percent.

1m behind would reduce the air resistance 1.8% (with 1 motor). This would imply winning several seconds on 10km.

(Of course, a motor in front has a much bigger impact.)
