And yes I understand the thinking that not all covered space is equal, the closer and edge is to the ground the less wind penetration. That said, if you assume a fixed angle of rainfall being driven by a wind, this isn't that hard to calculate. I suspect that we'll find the resulting superiority of one shape over another is still basically the same, at least as long as the ridgeline is perpendicular to the wind direction.

I haven't yet worked through the ridgeline parallel to the wind direction case but my suspicion is that it'll come out the same as well, since any loss of coverage at one end will be matched by an equivalent gain at the other.

Most interesting might be to work out coverage if we assume a given rain angle and a wind that shifts a full 360 degrees. (I'd calculate one side with a perpendicular situation and one with a parallel and then take it off twice as a reasonable estimate.)
