Haha - this forums post went from a simple guy who was angry about his 40 KW battery not being able to recover because he cannot balance his car, to a large rant from people wanting answers, ohh boy.
I think it is safe to assume that Tesla as an entity is very new... I will define it, in human terms, in its early childhood stage. It was an infant in 2006-2008 range when they introduced their roadster. After fixing their mistakes and understanding what they did right from wrong, they began to produce the Model S. The Model S has come out and Tesla is only beginning to walk. They probably do not fully understand the battery technology, especially lithium Ion cells, to the fullest extent. That is why there has not been any specific standards that are unified throughout all tech centers. It is more or less people reiterating known standards and knowledge. The Model S owners currently are essentially the lab rats of tomorrows generation, the Gen III vehicle. After a few years of recorded data from all Model S's under all climate conditions and the data crunched, reviewed, and finalized only then can Tesla make statements that will turn into standards for the next generation of vehicle. And until there is well over a decade of information and multiple generation models, can Tesla mature as a fully grown company.
An example of what I meant by collecting data from all Model S's, is if a owner charges at 50% every day compared to his neighbor who decides to charge at 90%, who will have more of a degradation? Another is if each charge at 90%, but both drive different - how does driving style affect degradation? These are all questions that cannot be answers at the moment. It will take years of data to prove any theories right versus wrong.
