the magic $10 billion number capping the size of the fund also seems curious because why would it be impervious to change over a period of 25 yrs in which the scale of trading volumes, market capitalization, etc. have all grown? also, groups of people don't perfectly share ideas, outlooks, etc. especially over time. Humans tend to argue, debate, tug of war. If this task (the puzzle they are solving) requires a team of people, the 1st tiers and 2nd tiers, again, how does that translate to a steady $10 billion "working capital" portfolio and steady returns over 25 yrs, this money sucking tick parasitically attaching itself to a stochastic market that has undergone vast changes, but itself staying so consistent?
