Data is data. At least we have some. Is it perfect, no... Is it better than nothing, probably. If nothing else, it reinforces the data from 2 years ago from the crappy concrete surface.

There has been one major change in R compounds since then, and one in ST really, so a wash makes sense to me.

I am not strongly advocating going to 2.5 seconds, but it should give the grumblers something to think about.

Get most of SECCS to show up for a club meeting and you could probably get it passed though .

And on weather conditions, etc. I just sent the following to the list as well...

Some people have asked if weather could have played a role or skewed
these numbers.

Yes, it could have, but for the most part it says the gap is even
bigger. For the Miatas and BMWs, the R compounds ran when cold, and
Street Tires when it was warmer, and they were still behind by those
margins.

There was no measurable precipitation for any run group according to
the weather source I have.

Fortunately, all the pairs ran on the same days. Times are at
approximately the second half of their run group based on 2 hour run
groups starting at 8:00 am each day.

BSP: Tues. East Heat 1= 56 degrees@9:00, Wed. West Heat 1 = 61 degrees@9:00
STU: Tues. West Heat 2= 69 degrees @11:00, Wed. East Heat 2 = 66 degrees @11:00
13 & 5 degrees warmer for ST, and still slower by over 3 seconds per 60.

CSP: Thur. West Heat 1= 49 degrees@9:00, Fri. East Heat 1 = 55 degrees@9:00
STS-2: Thur. East Heat 3= 57 degrees @1:00, Fri. West Heat 3 = 66 degrees @1:00
8 & 11 degrees warmer for ST, and still slower by well over 5 seconds per 60.

In DSP vs. STS the weather does slightly favor Race Tires.
DSP: Thur. East Heat 2= 66 degrees@11:00, Fri. West Heat 2 = 59 degrees@11:00
STS: Thur. East Heat 4= 69 degrees @3:00, Fri. West Heat 4 = 70 degrees @3:00
3 & 11 degrees warmer for R, but ST still slower by well over 2.5
seconds per 60.

If you would like to look at humidity and other weather factors, feel
free to check to this site for historical weather data for Topeka.
