I cannot believe you, Cent, of all, are asking this? There has to be a trap here.
However, since you are, may I ask what you think the gradient of climb is at Vs?
I'm sure you recall that best angle is (approx) Vmd? So, as long as Vmd is more than V2(Imp),
angle of climb will increase with speed. Once you exceed Vmd, you start to lose. My dusty brain cell tells me that best R o C is 1.32 Vmd? All to do with the curvy drag/speed graph and power/thrust maths. I'm sure a boffin will be along soon to cover the thread with calculus.
