If you look at the data the top 8 have an average of 3.39 deviation from first 50 fly to last 50 free. MA’s was 6.59? They have a very legitimate question about USRPT training.
If he is sticking strictly to USRPT training principles with (regards to distance of repeats) then he is going to run into trouble.
I have found that if you take the 50 split time of free and double it that should be the “no slower than” speed for n x 100s on 2:00/1:30 for IMers. So he should be 31.08 x 2 = 1:02.16 or 55.95 (converted from scm to scy) on that type set.
Just thinking out loud,
? I child proofed my house and they still get in 🙂
