setting a goal for the 1650

If my times on a set of 100s on 1:30 is 1:18 consistently, what should I expect to actually swim in a 1650? My best time thus far is a 21:56. Thanks! I did the math and if you can consistently swim 1:18 per 100, you would do a 21:45 for a 1650, so it sounds like you're right on the money.
