Motor is currently at 16000 rpm.

Is the ESC adding 1* of timing or is the ESC adding 16* of timing ?
I think I finally understand where you're confusion is stemming from. The slew rate is degrees added per 1000rpm. If the slew rate is 1*/1000rpm, it will add 1 additional degree every additional 1000rpm.

The slew rate is a slope - rise over run, not an equation based on the current motor rpm.

So going off your example, the esc will add 20* of timing total, but at 1*/1000rpm it will take a 20,000rpm increase to add 20* of timing.
