It fires every 20 seconds and it takes 2 iterations before it's basically unrecoverable. However, you aren't taking into the account in the "I think I fixed it factor" after the first couple iterations. It's not like they had all 3 minutes to figure it out and fix it. A good amount of time was wasted to see if the fixes had an effect. This answer does a good job of explaining all the things that the pilot has to do in those 3 minutes. https://www.quora.com/Why-did-the-pilots-on-the-Lion-Air-and-Ethiopian-Airlines-Boeing-737-MAX-flights-struggle-to-overcome-the-MCAS-systems-automatic-trim-adjustment-if-all-they-needed-to-do-was-grab-the-spinning-trim-wheel-with-their https://www.quora.com/Why-did-the-pilots-on-the-Lion-Air-and...
