I'd say 3% is pretty close. Pax shows a difference of about 1.5% between the classes but as has been said, CSR has a soft pax and CS seems to be a little too high. I definitely think they gained me at least a second on a 60 second course. I was actually using the harder of the 2 Hankook Z214 compounds so I had some time to gain in CSR, too.

I should just go look at the rulebook but aren't DOT tires required in prepared class too? Thought it was just modified that was open.
