Split times of the 500 free at AMYMSA Franklin

I had a master's swim meet yesterday and had a great time. In my first event, the 100-yard freestyle, I broke my old personal best by 2.02 seconds, lowering it to 1:03.57. That was an awesome feeling! My other events went well, too, including the 500-yard freestyle, which I finished just 2.4 seconds shy of my personal best. However, I wasn't necessarily wanting to set a record in that event. Instead, I have been working on my pacing. I tend to go too fast in the beginning and then tire out at the end. This is apparent in the graph below, with a steep increase in the time it takes each successive 50-yard lap in the pool (10x50=500 yards). I have plotted three of my swims from the 2016-17 season. In each swim I have slightly improved my pacing so that the line is not as steep. My faster and more experienced friend Daniel Pruzinsky has better pacing, as evidenced by the fourth, flatter line in the middle. I want to be like him, so there is more work for me to do.
