It would have been nice to see if the changes actually were noticeable or not. Yes, one version may be faster than another, but simply ordering a set of tests like that doesn't show if it is worth the trouble doing anything about it.
I have linked the data next to the graph, it's called "Raw Data". I'm unsure how best to represent it to show real differences though. The raw scores per test each on their own graph would be the most accurate way, but not very easy to read.
