Broken 200 free interval

If you were to do a broken 200 freestyle swim (scy) as 4 x 50 on (X) interval in a practice setting and add the total time for each of the four 50s, what interval would give you the best approximation of your 200 race time? The interval would depend on your speed, so perhaps I'm asking how much rest you should have between each 50. I recently did 4x50 on 0:45 and went 29, 30, 31, 30. I'm wondering how close I'll be to 2:00 in a race. Consider this: warm up easy do a few race pace 25's dry off put on a racing suit. Rest 15 minutes arrange for someone to time you and get your splits do 4 x 50 free fast at 200 race pace, 0 REST BETWEEN 50's, flip your turns, swim your 1st 50 easy speed, breathe a lot, & save your legs. try to keep your next three 50's around the same times. you'll find out how close to 2:00 you'll be. any rest between 50's just leads to self delusion
