Hi Cvetan and everybody

I have a question about the 1/2 cycle.
Suppose, for simplicity, that
at cycle 0 I have 10 knots.
At cycle 1, I have 9 Knots.
At cycle 2 I have, 8 Knots.
If I do a change between cycle 1 and cycle 2, which wind speed do I get at changing point?
9 knots, 8 knots or, 8.5 knots?

Assuming that the wind speed variation gradient is constant between "cycle 1" and "cycle 2", the speed would be 8.5 knots.
