How ttRating Works

What is an official time trial? Official means you completed the required number of consecutive incident free laps during a time trial session. For example, Mazda Raceway at Laguna Seca requires four consecutive incident free laps.

The simplest way to explain this is using a table. (See Below) 

Essentially, you get a session rating at a track each time you complete a time trial. This session rating depends on your time trial time compared to the time trial record for that car at that track.

Your last four time trial session ratings at a given track regardless of car are averaged to get your rating for that track. For each car you time trial at a track, youíre given a normalized number, and that number is reflected by a rating, for example 1600. Why doesnít it matter which car? Because within the formula, being x.xxx off the record in a Rookie Solstice can be equated to being x.xxx off the FSB200 record.

Your track rating from your 8 most recently visited tracks are averaged to give your overall time trial rating.

What if you havenít time trialed at 8 tracks? What happens here, is that youíre given the service wide average rating for the remaining tracks. So the table shows Driver A having time trialed at 4 tracks, leaving him 4 tracks at which he is getting the service average rating, for example, letís say the avg is 1600 for all other tracks.

Once you have time trialed at 8 tracks, your overall rating is more correct, because now you have 8 real ratings for 8 tracks, no service average ratings are included. Once you complete a time trial on a 9th track, only the 8 most recent are used, so in this case your first track would be dropped from the average.

Having the best time trial or being at the top percentile of the standings for a given week or track doesnít necessarily equate to a positive gain in ttRating points.
