PILOT_SPEED_UP not working as expected

Hi!
I wanted to limit the climb rate of my drone and naturally I tried to tweak the PILOT_SPEED_UP/DOWN parameters.
I tried changing them mid flight to react to obstacles on the ground (sudden down sonar jump) and when i look at the CTUN.Cr and dCr the are higher than the PILOT_SPEED_UP value.

These flights were limited to a PILOT_SPEED_UP value of 20:

Why isnt this parameter updating during flight?

Thanks,
