The car is running Carbotech XP10s and 245 RE71rs (koni yellow shock, swift spec r springs, camber at -3.2 fron and -2.3 rear in case you needed more). Pro drivers that have been in the car have complimented the suspension balance so I don't think it is an underdamping issue in the front.
What I am trying to understand is if it is time to step up the pads or is the delta pretty standard? The maximum braking reached was pretty consistent through each braking zone (including hard braking zones), so I don't think it is a braking application issue. Also, using the pedal dance.

Your phone GPS is only 1Hz. It might not be accurate enough for braking situation.
Cornering is more like a steady state and 1Hz might be less wrong.
If the app get acceleration from accelerometer, it's maybe the same, as you got more time to monitor the acceleration in a corner than in the braking zone.
Phone are great at giving lap time, but they suck at giving top speed, cornering speed and driving line. You need a 10Hz GPS for that.
