  "The mean of the top 50 growth rates" is a horrible abuse of statistics. No amount of ~pretty graphs will compensate for that.

    It doesn't 'prove' anything, but it does give a high level view of the overall level of revenue growth across years.

      Well obviously it doesn't "prove" anything, but I don't think it gives a "high level view" of what's happening either. You shouldn't take the mean of a highly non-normal distribution. It's virtually meaningless (no pun intended). When the population you're looking at is completely arbitrary anyway (top 50), the results are further nullified. And taking the mean of a group of percentages is... not wrong, but dangerous IMO.
