this isn't quite going to make sense at first (perhaps):Originally posted by bettysfetish
See if this is analogious; You want to know how many phone books one bullet will penitrate. You fire at one book(all measurments and volicities recorded) and it passes thru. Thru two books as well. Then three. If the "exiting" volocity of each firing compaired to one another a "decelleration rate" can be compiled, "BUT", your out of books. I think it would be simple to "Extrapolate" the results to detirmine how many more books we need, therefore we should be able to get results without completing the test "just because we can't forsee a roadblock to our experiment." Is "that" too far off the wall?
i can see how extrapolation to a few more books is less risky than extrapolation to a few billion books.
in other words, extrapolating well beyond available data is often risky. sometimes extrapolating even slightly beyond available data is risky. either way, extrapolation isn't absolute truth for sure.
