From my experience, if the Z is losing position, then reducing accel will definitely help.
However.
The fact that it appears to lose position, and then get back to position, really points to a mechanical issue to me.
If the Z were to lose steps, it's very unlikely that is will lose in one place, and then regain the exact same amount in another place. Typically, it'll do one of two things. Wither get deeper and deeper. Or slowly lift above the part and stop cutting.
What are the actual accel and velocity settings you're using?
