Okay, that's a new one..... Bear in mind that I'm not in any way included behind the scenes. All I know is from what I found in my own testing, so there is as always every chance that I'm monumentally wrong....again. However, with that caveat in place, the adaptive AI only writes indexes* during race conditions. Fixed AI levels will write ONE index at that level, while adaptive AI will keep adjusting the levels in the XML file until it reaches the limit (six or seven entries, depends a little on the track for some weird reason). Every car/track combo starts at 80. If the AI got creamed in the first race, it'll then go to 90 for your next start. (Btw, in your example the AI wasn't running at 90, that's just the index that got written after the race. It ran at 80, your NEXT race will be at 90.) If that still isn't enough it'll then go to around 100, but that depends a little on your own level. The closer the AI comes to your actual level, the shorter increments it'll increase by so it doesn't suddenly overshoot you. Example: Say your own level is approximately 115. The AI, on a fresh XML file, will start at 80. Then it'll go to 90. Then let's say 100, 107, 112, 113, etc. The exception is that if it hasn't reached a competitive level by the time it reaches the last entry available in the XML, it'll jump to 120. After the index has been filled it'll then start to replace the unused AI levels in it with entries closer to your level. Eventually ending up with a tightly grouped set of indexes around your personal level. The 'eventually' bit being why @pixeljetstream and myself are working (well sorta...) on how to get it competitive faster. If you only have one entry at 102, the only reason I can think of is that you at some point ran against fixed AI at level 102. That is the only way that I know of that will write a single index out of adaptive context. If that for some reason can't possibly have happened, then I'm completely stumped. One thing is for sure, the AI does NOT use entries from other car/track combos. Each combo is its own little world. *At some point someone will have to tell me the plural of index.
