My daughter has counties this weekend. Super excited for her and really pleased I've recently found this platform. Who has used the Phelps technique and felt the benefit?

100 free - 1:01.41 200 back - 2:24.98 (second place by miliseconds of the national champion) 50 fly - 32.26 200 free - 2:16.23 (was right after the 200 back so i was quite tired) 50 free - 28.54 (i was in lane 9 and the guy next to me done breastroke😭)
