No, but he does point out these are theoretical maximums to shoot for and base the calculations from. The title states "minimum" for the target cross sectional area so it follows that extremes are used.

I get that, but I'm just wondering if there based off too ideal engines to be useful to an average guy's engine even though as I pointed out in post #34 it basically matches what I would guesstimate my way. Even though my guesstimation based on a somewhat inefficient engine.
