Why can't I take a reading 90 degrees to my rifle and use that number? Isn't this the wind that my bullet will see? Why do i care what the full wind is unless that happens to be at 90 degrees?edge.

I think you mean Zero degrees - you want the POS component of the wind. The question is, will keeping the wind meter parallel with my POS give me the POS component (ie, the COS(alpha) of true wind speed). It depends on the geometry of the wind meter. On a unit like my
that's Omnidirectional, you obviously can't get the POS component. I'm guessing most wind meters have too much turbulence and would read load in comparison to the cos(alpha).
I think I'll add the -
Kestrel 2500NV Night Vision
to my wind bag collection. I'll be adding the Speedtech Wind Tunnel
( Meets NCAA Track and Field requirements and provides precise wind velocity in a specific direction for precision measurements. ) to test this conjecture.
BTW, the POS wind component at 45 degrees is not 1/2, but sqrt(2)/2 or aprox .707
