If you are going ALL OUT, i.e. "race pace", how will your 200 LCM time compare to your 225 SCY time?
200 m is about 218.72 yds, so 225 yds is about 6.28 yds longer than 200 m. How much time this converts to depends on how fast you are, of course, the faster you are, the less extra time the extra 6.28 yds will take.
BUT.
A 225 SCY has 8 turns whereas 200 LCM has only 3. For example, for my backstroke, I estimate that each turn cuts about 1s off my total time, so the extra 5 turns save about 5 seconds. If you have better turns, you'll save more time.
It looks like the two factors approximately cancel for me in backstroke. I haven't done the analysis for other strokes yet. I'd be interested to see results (and/or speculation) for other swimmers.
Had an interesting take on this last week. Our indoor pool was closed for work so we got to swim outside for the week in the 20 yard pool. Now why, in the 21st century, anyone built a 20 yard pool is something we all wonder about here, but anyway, here is what we noticed.
My little group routinely does a set of 8x250 in the follow pattern
100 on 1:00
followed by 3x50 on a minute recovery
8 times
or
200 on 2:00
followed by a 200 or so recovery.
twice and then do the 100 on 1:00 set above four times.
During each set, only person is going "hard" while the other one or two are recovering.
Anyway, doing this set last week in the 20 yard pool we noticed our 100s (with 4 turns now instead of 3) were about a second or so faster (both for freestyle and fly. I didn't do any backstroke as there are no flags outside).
The 200s we did were slower by at least 1 to 2 seconds (2:06 or so vs the 2:04 we could normally do). With the extra turns we could really feel the oxygen debt later in the swim by spending all of that extra time underwater off of the extra turns. (9 turns vs 7).
