I put an eagletree up not that long ago showing that an lvc of 3.2 on the MMM still allows the pack to get under 6v under load. I have reset my LVC to 3.4 v / cell.
This graph shows pack voltage with a 3.2v/cell lipo cut off, it still drops below under load.
It may not kill the battery the 1st, 2nd or even 20th time but it all contributes until one time you reach the point of no return and it's puffin time!
