Two dumb questions about the math (because I suck at math).
- Do you mean by "best estimate" the best case scenario, or something
else (perhaps "the most accurate")?
- Is computing based on linear history a good enough approximation?
I am not advocating to make things more precise nor saying your math is
flawed. I'd prefer simpler code for things like this --- after all, my
understanding of this whole exercise is to give "this is more or less the
number you should expect" ballpack figure and nothing more (correct me if
that is not what you are aiming for).
