ファイナルファンタジーのソフトキャップ：次の1ポイントが無駄になる境目

Only until it reaches its limit. After that the same attribute is often the worst place on the board for a point, and the strong build stops being the best one by a measurable amount.

With an attribute giving three a point up to twenty and one after, against a second giving two up to fifteen, forty points split well are worth ninety-five and poured into the first are worth eighty.

Because once both attributes are past their limits every further point is worth the same wherever it goes, so no new damage can accumulate.

The whole penalty is paid in the stretch between the first limit and the second, which is also why the answer changes so much when a limit moves.

Any of them, and that is a real answer rather than a hedge. The leftover points past both limits are worth the same wherever they land, so spend them on whatever the numbers here cannot see.

The count is shown precisely so you know how much freedom you actually have instead of guessing that there is one right build.

That each attribute pays one rate up to its limit and another after it, that the two do not interact, and that the totals are what you are trying to maximise.

It does not assume the second rate is the smaller one, which is why it checks every split rather than taking the greedy path. Anything a build is besides a total sits outside it.
