Instead of trying to obtain a change in primary stat, s1, via derivatives, in this case it is cleaner to set the %stat as a separate variable, then obtain the partial derivatives from there on.
Or in this case, since there's little point trying to complicate things via partials (although it is legit), a simple (1 + K + deltaK)*s1 will do, where K is the %stat in decimals, assuming you're only doing a single-variable change.
Maybe someone should just bother to do a spreadsheet that combines all the partial derivatives together to compare two items up for grabs.
