Great post! A couple of nitpicks on the data presentation for the sake of making it even better: 1. You don't have enough data to warrant 5 significant digits in the percentages, and even if you did, is it really relevant? 2. The points in your plot are interpolated using some sort of spline, why? If the answer is: because it looks better than jagged edges, then you should probably remove the spline, because you're effectively adding extraneous information. On the other hand a linear trend line could be nice here.
