I think you missed my point. Notice my example does not use values
from the table. Is there a reason not to use the PHY with 2000mv? Or
does it break when you don't use one of the 4 listed voltages?
I was wanting you to implement some formula, which given the voltage
and percentage slowdown, returns the magic number. Hence the comment:

You need to do integer arithmetic, which is why i suggested mV, not V.
