@timurrrr do you have wheel speed and brake pressure traces?
Pressure traces yes, wheel speeds not yet.

I only had the car assembled a couple of days before the track day, and had very little time to set up data logging.
I ended up missing my first session because my old Braille battery died while I was sanity checking my data setup with the engine off

I can tell from the feel and the sound that I heard that I was indeed engaging ABS more often than I should have. "I have a lead foot".

That's hard to believe, as I gently street drove for a few days on the pads that came with the kit before putting C1's in and going for the high intensity part of the bed-in process.
(I didn't just slap the kit on and went to the track)

Unfortunately I didn't take all the photos I could, but here's a segment of one of the rotors ~40 minutes driving time before I put the C1 pads in:



The high spot was removed by lightly touching it with a screwdriver.
