* The plots are based on best fit regression lines of the data while the percentiles are based on the un-modified data (without a best fit smoothing function). Therefore, the dot on the graphs may be different compared to the percentiles listed. The percentiles are a more accurate estimate for individual data and the plots should be regarded as supplementary.
