 --Diminishing-returns method of scaling combat stats, observing this rule: the first twenty ranks cost 1 point each, the second twenty cost two each, and so on. This is much, much better for players than some logarithmic mess, since they always know exactly what's going on, and there are nice breakpoints to strive for.
