Someone(s) likely has already discussed the issue of IF the Model 3 actually has only one size battery pack (the smaller one being software locked out). I however would like to ask a slightly different question, but first a diversion... For those of you who are not familiar with what an Actuary is, I suggest a quick look at this Wikipedia article: https://en.wikipedia.org/wiki/Actuary I can easily imagine that at some point there must have been an Actuary at Tesla who sat down with all the available numbers, forecasts, costs, and so forth and crunched the numbers to figure out if it would make more sense to... * sell two entirely different battery packs for the model 3 (as we now believe is happening) _OR_ * market/sell two battery packs, but in reality it's just ONE battery pack that is software locked into two sizes. What I'd like to know is... What are those types or categories of numbers that an Actuary would use for such a calculation? and What are the actual values in each of those categories? i.e.: How do we the members of the general public try to replicate how such a decision could have been made? 17.088 ^2 .
