I need the BRI numbers for the new classes.........

If you take my time in the 944 spec and apply the BRI you get a corrected time of 88.4. My corrected time in my turbo is 88.4. So there is at least some accuracy in the BRI

Likewise Jad, I would have been 8 with my Spec BRI and was 10 with the RSA. So maybe that thing is more accurate than Tom thinks?

70th on the day and 70th on the BRI...

NS/S was modified last year to accomodate the GT2/GT3, you should use that number (1.050) and revert NS/S to its old number of 1.033.

Don't take my disclaimers about the BRI wrong, David, I really like the index and was a proponent of its development, and I think Carl did an excellent job of leveling the field, as it is a very difficult proposition. It is a moving target, though, and we need to refine it annually, which is what the SCCA does. It is going to need revision for the new classes, and I hope Carl will have the time to work on it again.

I have to poo-poo its accuracy in order to appear humble about doing so well on the BRI previously. I would have had an 84.68 at this event with the same index as last year, so I feel pretty good about my drive on Sunday, in a 38-year old car on street tires.

Martin beat me by 8 hundredths in the actual timing, and by 8 hundredths in the BRI

If only I hadn't DNF'd the first run...

Ummm Bob, aren't you two in the same class? So your index is the same? Seems to make sense that the difference would be the same also...

I updated the BRI tables so that everyone (particularly in O and P class) would have a BRI number. The set of BRI numbers are new for 2005. The previous BRI numbers will remain for prior years as these BRI indices are date ranged.

Carl is working on creating some indices for these new classes and when he completes this prior to the next auto-x I will update the current BRI tables to reflect them. That is the latest for now..................

I am happy with this BRI!

Now if Bill Ibbetson would just stop driving that 968 WAY beyond it's limits, maybe I could move up another notch...

Something is screwy with the databases or factors, Kary, I am getting some whacky numbers (like 11 seconds for a corrected lap time in CSS in the 7/26/03 event, because of an index shown at .0975 instead of .975) and other dates that return "no info" when the BRI position is clicked on from the results table (like for the 2/21/04 event.)

I think you might have some typos in your tables somewhere?

Tom, you get what you paid for with this database I will have to look at it when I get time to determine what the issue might be. What do you want for free?

Ok, I took a quick look. The issue was in the first date range of BRI indices the CSS CSSL was set to 0.0975 rather than 0.975. That is why the times were screwy for the BRI. It should be fine for the earlier BRI date ranges (i.e. before 7/2004).

Still get what you paid for

You're providing a great resource for free, Kary, and I appreciate all your efforts on it, as do many others, I'm sure. Take all the time you need, I'm not complaining!

I realized the events where I was getting "no info" on the BRI were rainouts. DUH!

Kary: I have put in a suggestion with the board to double your current pay. Just a token of my appreciation for your efforts.
