I'm not really interested in arguing about these numbers, it's not really relevant to my point. I was basing this off of https://www.teamblind.com/article/google-engineer---total-co... where 250-350 includes the majority of L4 and L5 engineers. Based on this your numbers look off by one level or so, at least for Google. But again, I don't think this is very important for my point.
