For a start,
Why do a broken 200 as opposed to a regular 200? What is the particular advantage of breaking up the distance (or any distance for that matter)?
Is it better to break it up at the 50 or the 100?
What is the ideal rest time between 50's and 100's within a broken 200?
What is the ideal rest time between broken 200's within a set?
What is the ideal number of 200's to do in a set?
Are the accumulated times of a broken 200 an accurate indicator of how fast you can actually go?
If breaking it up at the 50, how much time should be added on for each flip turn?
How many broken 200's should I be able to do at a specific time to be confident that I could repeat that time in a race?
I'll mention what my high school practices were. Sometime during practice, one set of 5 x 200s on 3 min, broken. 30 seconds rest, either 10 seconds between each 50, or 100 (15 sec)/50 (10 sec)/25 (5 sec)/ 25. The rest during the swim allows your body to get used to swimming closer to race pace.
Pacing within the 200 should be even, with the overall time (with rest time subtracted) within 5-10 seconds of meet speed. (Our team managers wrote down the 200 times, so we paid attention to keeping it constant.) When it gets to taper time, increase the rest, reduce the repeats, and the overall time should eventually reach race speed.
