i enjoy reading/listening to discussions between folks with expertise in similar fields and why/why not to clarify knowledge. I place a greater weight emphasis on both your's and Randys remarks as opposed to Paulo or MS or others with barely a passing aquaintance of the field(s). sometimes a graceful exit is best as you cannot win all the time, but SA seems less "stridant" as one person remarked perhaps.Nonsense from bulls is no better than nonsense from bears and I'll call out both when appropriate. I have no problem if a bear credits me with speaking the truth. Randy's response further proves he doesn't know much at all about cell production.
Cells are charged and most likely measured before going into the aging room, there is no point in aging a bad cell. They are likely tested again after aging to make sure they are up to spec because you don't want to put a bad cell into a module. My speculation is that the measuring technology developed by Prof. Jeff Dahn using coulombic efficiency is used to measure and grade cells.
meanwhile, those shorts are hurting puppies with TSLA up ~$50 since december 1st.. I suspect their options are expiring worthless at best
