You're right, but since 10 > 5 the pilot should always be able to "win". You can see it happening in the Lion Air flight: https://spectrum.ieee.org/image/MzE4

I count 20 cycles of MCAS -> Pilot correction. It's not clear why the pilots lost the 21st cycle. It could be that they stopped making corrections or another yet to be identified airplane failure.
- phire 8y agoThe MCAS activation just after 23:33:53 pushes the stabiliser down slightly further than it did at any point previously. After this point, the stabiliser looks like it stops responding to trim up commands. The pilots do a few more trim up commands, but the is never a significant upwards response again. Perhaps this is because the pilot's trim up commands appear to be shorter, or perhaps the pilots are pressing the trim up button, hearing a loud girding noise from the electric trim motor as nothing moves, so they stop holding trim up. With all this talk about aerodynamic forces being too strong on the Ethiopian Airlines flight for pilots to manually trim up, I'm wondering if the Lion Air flight experienced aerodynamic forces so strong that even the electric motor was struggling to trim up.
