talking of swimming wording ... is a stroke per arm or per two arms so left right is 1 stroke? If I count every right arm entry I do 16 which given I am slooooooooow seems very low to say I do 16 strokes per length (but that's what my 910 says I do!)
EP stroke rate is counted as every right arm, so 16 for 25m doing front crawl seems OK, my average is 13 or 14, but on a really good day I can do 12. Try keeping the outstretched arm/hand out in front, in the water for a second before starting to bring the hand and arm through the water, that makes the difference for me. I keep hearing about gliding and think streamlined.
