One question. You maintained the pace of :20 per 25 neatly from the 25s to the 75s. On the 100s, your pace jumped to :22 per 25. What happened there?
Your Kaizen goal for this set could be to hold the :20 per 25 steadily through the 125s, then gradually increase pace on the way down.
Excellent set plan though. There are so many opportunities to use a basic pyramid design like this to work on all the aspects of effective, economic swimming.
Pace (which, if SPL is held constant, means adjusting SR)
Overall set length (i.e. when you've improved all four of the above ingredients, add 4 x 150 in the middle.)
