I was planning something similar for tomorrow's workout. I'm not very fast (optimistically 1:25 for 100bk right now). If I use 1:20 as my goal, I was thinking of 20x25 on 50s with a target time of :20 per 25, but maybe on 60s would be better (2:1 rest/work ratio). (An interval of 55s or 65s would be easier to count though...)
