i totally agree, improvements in her technique would probably get her the greatest gains. I just dont know anything about swimming, so I have to rely on her coach for that. Also, she is not that fast to begin with. As an example, first place in freestyle was 36 seconds, her time was around 45.
She just had city, her last meet. She did tabata style interval training 3 -4 times a week after practice (for about 3 weeks I think). I really have to give her some props here, she really drove this training routine after I suggested it (ie I did not have to prod her to get her to keep with it) and kept focused on beating her times at city.

I know I am biased as her father here, but those improvements seem pretty amazing to me. Her times were essentially flat (ie no noticeable improvement) for the first two months of the season. So these improvements are the result of her efforts for the last three weeks.
She still slowed down on the second leg of her freestyle, but on the back and breast, she kept the same pace all the way through.
