The VC is doing, give or take, the same deal 10-20x in a portfolio. If you talk about that 1% becoming a norm, then it really moves the dial 5-10% on the total return for the VC.
A founding team should be owning 60-80% of the company after that transaction. Meaning, the 1% ownership difference is something like 1.3% of the founders' total return.
If you're going to try to do math on it, be fair and real.
