Well the odd things is that most if not all admit that the 18.5 degree sweep was too slight to achieve any real significant advantage in the mach number..
Even those who don't agree on the reason for the wing sweep admit that..
So he is really in the minority with this line of reasoning..
As for his claim that I am
focusing on minutiae an taking Jenkins out of context to fit my agenda
Here is what Jenkins had to say about 18.5 degree sweep angle and associated mach number (in

The Me 262 had a slightly higher critical Mach number-0.83 Mach versus the handbook limit of 0.80 Mach for the P-80A--but the difference was of little value in the real world since the Me 262 could only reach that velocity in a dive, whereas the P-80A could do it in level flight. However, despite the fact that the Me 262 was almost 2,000 pounds heavier than the P-80A, the German aircraft accelerated quicker and had approximately the same climb performance. During the tests it was found that the slightly swept wing of the Me 262 provided no useful reduction in drag, mainly because the triangular cross-section of the fuselage created so much base drag that nothing could really help much. The swept wing did not change the critical Mach number by a measurable amount, and certainly did not help performance in the low transonic region where the Me 262 was particularly unstable. The P-80A had much better handling characteristics than the Me 262, largely because it was more refined aerodynamically and had its thrust vector on the centerline of the aircraft instead of at the quarter-span of each wing.

As you can see Jenkin's comment consist of both pros and cons, and his comment wrt mach benefits of the Me262 18.5 degree wing sweep agree with the majority.
So as you can see from Jenkins comments, nothing was taken out of context on my part, no agenda on my part, no opinion on my part
All I am doing is agreeing with Jenkins comments!
