I ended up with 25.675/56.881.  I feel more competitive with the stickier tires, I play a lot of two player with that format.  I wish my splits reflected the sensation but I only had a couple shots at it, no time earlier in the week.  Great week, love the handicapping.
Since I can't sleep, I ran a bit more-25.866/57.052 but 0.6 better at the finish so there you go.
