Interesting analysis but the statistic I find most disturbing (and selective) is the "average" value of startups funded. What would be more informative is the mean value. I'm guessing the mean value would be extremely lower since most of the total value is made by a few outliers on the top end.

By taking the average value in this case, it's likely giving an inaccurate picture of what the average YC funded company is actually worth.

Just a thought. I could be wrong assuming most of the total value does not come from outliers but my sense is that I'm right based on the news I've seen around YC companies.
