The new 315 R7s were worth 2.5 seconds over 305 PZero Slicks at Willow Springs, but the PZeros had 10 cycles put on them by me after I bought them used, and at a new track for me.
I'll be at a familiar track this weekend and will have some times for a more direct comparison--but I think I will set some new personal bests.
