The comparison of 15% for 150k vs 22% for 813k is unfair because it suggests that $5m valuation is entirely because of YC. The fact that many YC companies don't raise clearly indicates that YC helps but not a sufficient factor.
Since YC companies' approx valuation is $5m, the 80k note will take about 1.6% equity. So I would say YC is offering 98k for 8.6% (18k + 80k for 7% + 1.6%).
