so it would be 10x25 holding 11 on a 30 second interval. i believe this is flawed for one of two reasons. the first is that your 50 free incorporates a dive into the race. its kind of hard to touch, get out, get up on the blocks and be ready to go in 20 seconds. the second reason - lets just say that this swimmer can get out and be ready in 20 seconds to go again from the block - what happens when you get to the other end and there is no block?
With that amount of rest starting from the blocks is not realistic. I would use the estimated second 25 time for your 50 rather than an average, so maybe try to hold 12 seconds. Same thing for a set where the goal is to hold 50s at 100 pace. Use the goal time for your second 50 of the 100 rather than half the total time.
