But JOCOSA has still some advantages over Felix15 for example. In most random tracks Felix beats JOCOSA but in one out of say 20 JOCOSA is faster. I have seen that when a corner is less than 90 degrees JOCOSA can take it faster. In a track that contains only 90 degree or less curves, JOCOSA will allways beat Felix (unless passing is a factor). For corners longer than 90 degrees JOCOSA brakes much earlier than Felix15 who brakes very late an until the middle of every corner. JOCOSA needs to get the right speed just before it starts to steer, loosing a lot of time. JOCOSA allways follows circular arcs for every corner (as you said Tim). Some sequences of corners are still to be analyzed to make an optimal path. This may be (or not) a good clue for all of you. Greetings, Jorge.
