Uhm, a point is a point, it always goes to total as well as champ data (and optionally also to playing/driving), regardless of its origin. Note that "champ" in this sense means simply everyday racing, just limited to one week or one month, with winner maybe announced in welcome messages or on a Web page. If you want to run a real championship, say with special races once a week, you may turn on champ points gathering only for the event and also disable all special points (climber, improvement, good laps) for this special occassion.
Yes, good requirement, I'll write it somewhere near top of my TODO list. I'd also like to add configurable rating decrease on each forced spectating and kick/ban.
The problem is LFS may be reporting pretty weird lap times e.g. in practice and to have reasonable data it is best to simply ignore 1st lap. In race this works well and my tests show it works (after latest updates) even in qualification and practice, so I'm a bit surprised it is still reported as a bug on the LFS Spain servers. Maybe just some updates confusion... I'll do some more tests
