Looking at the 2 areas you mentioned I see that the motors are not balanced which would be consistent with the wind you said you were flying in.
At takeoff you have a motor bias, but flying the bias changes. Seems consistent with pushing into the breeze.
I would, however, check your copter balance and that all motors are vertical, as you probably have.
The IMU graphs do show a variation.
Zooming in and comparing the Acc 1 & 2 to a PH2.1(top) PH1 (middle) and yours (bottom) it seems like IMU2 is picking up a lot more vibration than IMU1.
Can’t really explain why.
