Why was the BF109 so slow compared with the P51_ [360p]

I am not claiming to have produced this, I am uploading this for the quality of the analysis of the subject. This guy has gone into huge amounts of detail, to illustrate the point. It's HOW to illustrate the point, where in the lessons lie.

So rather than run around screeching, "All women are retarded arseholes" - which is mostly true, the effective understanding, and use of the information, comes from understanding the details, and the connections between them - and the big world coming in, then processing it through the details, and then outputting an effective understanding of the issues.
