Hi guys

I'm trying to understand the dead downwind faster than the wind thing.

Can anyone on here say that they have definitely achieved any of these speeds?

at 110 degrees 2.92 times the speed of the wind
at 120 degrees 2 times the speed of the wind
at 130 degrees 1.55 times the speed of the wind

eg going 40 knots in 25.8 knots of wind at 130 would count
going 30 knots in 19.4 knots of wind at 130 would count
going 20 knots in 12.9 knots of wind at 130 would count
