Comment (by bookmoons):
I'm getting some numbers from the TIMER macros. But the run counts bounce
up and down. Does that seem right?
> 3521 UNITS in hscale, 32 runs, 0 skips
> 6714 UNITS in hscale, 64 runs, 0 skips
> 6456 UNITS in hscale, 128 runs, 0 skips
> 3182 UNITS in hscale, 64 runs, 0 skips
> 3344 UNITS in hscale, 64 runs, 0 skips
> 3375 UNITS in hscale, 128 runs, 0 skips
> 3419 UNITS in hscale, 128 runs, 0 skips
> 6693 UNITS in hscale, 255 runs, 1 skips
What I've done is wrap the callsites as shown above. There are 4 of them,
all through function pointers. I gave all 4 the same name "hscale".
