1. MCAS activation is not continuous, it's bursts.
2. The 737 trim system likes to provide bursts of random trim at certain times (STS) so bursts are considered normal.

This is why the Boeing excuse "they should have done the runaway stab QRH to fix the MCAS problem" is a load of utter nonsense. 737 Driver - pinning this on lack of airmanship will costs lives in the future.

Back in November 2018 Boeing issued a bulletin about the MCAS Stab Trim problem and many airlines responded by removing the word “CONTINUOUS” from the Runaway Stabilizer checklist.
