Acro mode control deflection

Hello,
I’ve setup a couple of planes to use Manual and Acro modes, and have noticed some odd control surface behavior when in Acro mode. When in Manual the control surfaces move smoothly to full deflection in proportion with the stick movement. When in Acro mode the control surfaces move very rapidly from 0 to max and it appears that only 50% of the stick travel is being used. This is setup with the default PIDs. What am I doing wrong? Thanks

Edit: It seems that the default P setting at 1.0 is what’s causing the issue. 0.2 seems to be a workable setting for the start.
