See, so the Mustangs were not a definate saviour. German aircraft always got through. You think too clean cut, RG. If it was so simple for the Mustang to dive, bounce, climb and re-adjust it'd be invincible.
Say we have Spitfire Mk. XIV and Spitfire Mk. VI (High Alt) flying high cover. The Mustangs aren't going to be able to stop the attack. Why? Because both groups of Spitfire aren't going to follow.
I never said they would be 100% effective. Any time the two combatants are roughly competitive, some are going to get through. Escort is by definition more difficult than interception, so you need more escorts than the number of interceptors to be stopped. The point is that the P-51 was the better escort/patrol plane than the Spitfire.
As for your follow argument - you are assuming there are more Spitfires than P-51's? If so then of course some are likely to get through!
For the Spitfire vs. the P-51, you failed to suggest their counter tactic. It is rather simple. The Spitfire XIV was able to fight more effectively at 35,000 feet than the P-51. By climbing to such altitude they could harry the P-51's and drive them off, and then dive into the bombers. Timing would be critical and difficult to manage given the very short endurance, but it could be done - sometimes it would work out, sometimes it wouldn't. The issue then becomes the fact that the Spitfire lacks the firepower to take down B-17s reliably in a single pass - but that's another issue.
So what it comes down to is the Spitfires need to get above the P-51's, the P-51's need to prevent them from doing so. Either result could be achieved depending on circumstance, but all things considered the P-51 is probably more likely to succeed if available in sufficient numbers (ie: something more than 1:1 which would be expected as P-51's were easier to build than Spitfires).

Erich-
Sure the Luftwaffe' was able to mount a few sorties where they had some measure of success. But compared to the overall numbers of bombers flying on those days, they were tiny. Looking at single bomber formations that the luftwaffe' upon which concetrated its attacks and trying to use that as a reference is totally playing with numbers, you have to look at the total number of heavies in the air that day. And what you've failed to list is the losses suffered by the Luftwaffe' to achieve those relatively few kills.
