Swim Golf

I have started to do some Swim Golf exercises during my training and have a better score than I could ever hope to have as a golfer. I typically score anywhere from 69 to 76 depending on how tired I am. I typically take 14 strokes on the first 25 yds and then 16 on the backside (due to not getting a really strong pushoff on my flip turn). I typically swim the 50 yards in right around 40 seconds. When I start to tire it goes up to 43, 44...you get the idea. Does anyone else do swim golf exercises? If so, how many strokes do you tend to take during each length? Whenever I try to reduce the stroke count my time tends to go up. I think 12 or 13 may be feasible as I can do those stroke counts for 25 yards but I am not sure if those types of stroke counts will be conducive to also cutting down the time it takes me to cover the 50 yards.
