Damaged cells during high current discharge test? Strange behaviour afterwards...

A few videos back, we have tested the PALO LiFePO4 cells and did a high current discharge test with 35A as per the specifications for these cells. This resulted in some questions as if this has damaged the cells and they now have less capacity as before already.
We do the test today and capacity test all 4 cells again and compare the results with the first run from when they were new.
We also do a full 4s/12V capacity test afterwards to check what capacity we would get out of a 4s battery configuration. Wait! During this test we can actually see something with the cells we tested with the high current test a few videos back.
Are they damaged or do we just see some random behaviour?
