Jacob, I think Dave did about as good a job as can be done of putting the 25 years of study information in about as simple terms as possible. It's not a simple topic, and can't be boiled down to a couple of catchy sound bites.
Since you're in North Alabama, perhaps we can get together sometime, during one of my Stateside visits. If you're truly interested in understanding them; and we can work out a way get together sometime; I'd be happy to try and explain the study results first hand.
The Updates are, indeed, very detailed, and far more complicated reading than Dave's summary in TBM. That's intentional. They not only give 'the results', they delineate the specifics of each set of testing parameters and the precise results of each.
The Updates are not intended to provide results in lay terms, but rather to expand the understanding for those technically inclined. They are also there to provide enough detailed specifics, and the theory behind them, to permit any other person who wishes to do research on arrow terminal performance a basis permitting direct comparisons with whatever results they might obtain.
If the Syudy results are presented in a simplistic manner, without supporting methodology and results, they become nothing more than opinion. What is truly complex can only be distilled to its basic components without losing its integrity.

ps: For what it's worth, my education is totally the product of what America's public schools once offered to everyone ... before 'political correctness' replaced 'student correctness'; and the 3-R's were force to take a backseat to the new R - 'student's rights'!
