TÜV report – Question about braking values (Ant and Ant min)

Hello, I just have the old TÜV report of a (potentially) new car in front of me. For this I have one/two questions about the braking values. For the parking brake the values are 248 and 222 daN for the 2nd axle. This results in a deceleration of 19.4 % (m=2402kg). For the service brake were read for the 1st axle 289 and 294 daN, for the 2nd axle 205 and 204 daN. Strangely, a deceleration for the BBA was not specified (I come to a deceleration of about 40%, However, there is still a print specification px (in bar) with 25.0 and 48.1 and a value F min (in daN) of 328 and 245. Furthermore, there are percentages of Ant (73.3% and 26.7%) and Ant min (52% and 19%). The first value for px, F min, Ant and Ant mnin always refers to the first axis, the second to the second axis. If someone has an idea of what px, F min, Ant and Ant min mean and how it can be seen from the fact that the TÜV has reached minimum value, the TÜV has reached minimum value. e? Google has unfortunately not yielded anything :/.
