relationship between fly and free

I too feel stronger and feel faster in freestyle since training more fly. Objectively, I can now make some freestyle intervals that I have never been able to do before, ever. I feel that this mainly due to the the fact that I find freestyle the most physically taxing stroke to swim at medium to high intensities. In the past, I believe I was actually overtraining freestyle and it had a negative impact on my freestyle performance. For me, swimming fly has definitely helped my freestyle. However, conclusion begs the following 2 questions: 1) Was it actually the fly, or was it simply swimming less freestyle that actually helped? 2) Could the same/or better improvements in freestyle be made with swimming more backstroke or breaststroke, or doing something totally different? I feel that my freestyle improvements were 50% due to swimming more fly, and 50% due to not swimming freestyle. Further, I would suggest that for me, neither backstroke nor breaststroke nor any other activity could have produced these freestyle results. I suspect that some people may efficiently (and possibly most efficiently) improve their freestyle by swimming more fly. This is likely a small group of people, and I would never suggest that most people can efficiently improve their freestyle with swimming more fly.
