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.
