Have this 30% have actually been measured on such applications?

If softfp is already 10x faster, does the additional 30% between softfp
and hardfp really worth it? Do we need to switch to hardfp instead of
softfp, while only the second one needs a new port?

Picking the right name is probably lest than 0.0001% of the work...
