Just make sure you don't get too much VD at the motor peckerheads or you will have longer starting times. Another problem with using the smallest allowable size is when the specific installation is far from the source and the starter is located at that far end!
That's where "design" comes into play.

I try to avoid doing stuff like this that is likely to confuse someone at some point.

It is easier to just say 14 awg=15A, 12 awg=20A, and 10 awg =30A.

The difference in the installed cost is usually not enough to make it worth worrying about unnecessarily up-sizing a wire now and then.
