Things that could make it interesting are:
-Possibility that each player be compared to any other. Now we have possibility to compare only players who played together at the same time, but if the ranking worked on some other principles, any kind of comparison would be possible. I guess, number of tracks must be limited for that (like on DIT). About 10 tracks, 1 per week.
-Automated results updating. The ranking should be linked to the autoserver (like on DIT). It would give a possibility for any player to get on the list easily. In some short time ranking would have a lot of players, so all those graphs and comparisons will be really accurate and interesting to fallow.
-In order to make it more interesting, autoserver should show live results too.
-Point system probably must be changed. Percent of best lap time (or 3 laps, like in quali for the last F1 season) will probably be the best choice for determination of the ranking. In order to make it more satisfied for non-wankers, maybe the best choice is 10 laps of 11. First lap would be just for a warming up and finding position for a big fast lap combo. That would be pretty similar to IRT where consistency is crucial. But, for sure, it must be tested at first. It could be boring maybe, with even bigger luck factor (players will have to lose a lot of time to get a desired position). In that case, 1 best lap would be the best (It's kinda the most dynamic). 10 of 11 laps, from other side, makes players always possible to improve, which is better in long terms. In that case even pros will feel the need to play it more, cause it's easier to improve 10/11, than 1/11. But, laggy people would probably not like it.
-All statistics from DIT ranking should be included (all laptimes for each car and overall etc) with possibility of comparing.
-Team statistics, skill levels for players (When some player manage to get a new level, it could be showed live in autoserver in some "news" section for example).
-Country flags should be added.
If T could already to build this existing IRT ranking, I'm sure that all those changes would be easy for him to do too.
