Dave, that is correct, but the view of some in SAS, which I think is correct, is that the TD AI mod is superior to Cert's, and they may replace the latter with the TD ai in their ai package. Great work, and something to look forward to.
Cert was no FM guy or even a programmer. He was just a modder who kind of fell into a good thing. He knew how to edit the AI settings and just changed some of the basic numbers. However, since he was the only one doing such things, he became an instant folk hero.
He was soon inundated with so many requests to change even more of the AI, he must have realized he was in over his head. During this time his forum appearances declined until he simply disappeared from the scene. To me, it seemed like he really did not possess the necessary knowledge of the code to make any more relevant changes. In reality, the Cert AI was really not much different than Oleg's AI. It reduced the hated barrel-rolling and a couple of other small issues.
The 4.11 patch is a major overhaul of the AI. It's like nothing else that's come before it. If you spend any time at all with the new AI, this is immediately apparent.
So yes, the 4.11 AI is easily superior to any AI mod out there right now.
Sure, it has some quirks, like the 'checking 6' maneuvers. However, these issues may be addressed in future updates.
