So the typical household screen is not in the same ball park as one we would consider using for a grill block.
your not wrong, but how much open area do you believe the .13 has ?
.13 is designated for mites and other insects smaller than a flea, and has en effective coverage area of about 34%
no matter how you cut it, how many graphs you post, how many equations and how you arrange them, it isnt going to change a thing.
you keep forgetting I bring "real" world experience to the table, I do this for a living and have done so for more than 12 yrs.
as I stated, and will continue to state, minus a 45* / your not going to see much benefit over stock.
prove me wrong, get some screen, put on the front of your vehicle and post some real world data.

but, to prove it, you going to have to rig something up to put that screen at a straight on surface, that or you should go ahead and concede defeat.
(BTW, that is a trick challenge, and I'll even tell you why. Ive already done it, it made 0 improvement on my 99 Ranger XLT)
