Does that set address your concerns?
I'm not sure that does, but how about this?
Race-pace Set 2: 30 x 25 m butterfly or breaststroke
at 100 m race-pace (include underwater work).
On 45 seconds
So this one is more like a 2:1 rest to work ratio at very close to max speed. I would consider this an anaerobic set for sure.
