Review on Fast mission of Quadcopter

Hello,
I have done a fast missions on my copter.
WPNAV_ACCEL=2000;
WPNAV_JERK=16;
WPNAV_VEL=4000;
ANGLE_MAX=4500 (I donot want to go beyond this even if I can achieve higher speed)

When my quad is about to reach the waypoint (deceleration) I am seeing huge spike in VIBE.Z and VIBE.Y
My notch filter setting minimum frequency is 100Hz and bandwidth=25Hz. (One notch per motor) as suggested by @xfacta
Can anyone please review my Log and comment on stability of quadcopter and about the spike in vibration?
