Tough call.
Not fixing is bad, fixing is worse yet.
I'd simply add new entries, so the result sheet will show both "Sharpen Image" and "Sharpen Image (New)". May be, even two separate sections in the report, with separate aggregate scores - FP(legacy) and FP2013.

Not that I personally care. I don't even look at FP section of geekbench. It's too "microbenchy" for my liking.
Not that I have something against "microbenchy" microbenchmarks in general. In fact I like them and had written many myself. But, IMHO, "microbenchy" microbenchmarks absolutely have to be open-source and are 100% useless otherwise.

Yes, now it's cleared. Which does not help the outcome.
