The trick is, it's the start month's number of days that matters. Since the prorated period 03/01/2017 - 03/15/2017 is actually the end of a full period before the next one starts, the full period would be 02/16/2017 - 03/15/2017.
And since the start month is February, and it's number of days is 28, that will be used in the proration formula:
31 / 28 * 15 = 16.6071428
... that is indeed 16.61 if we round it up to two decimals.
