I would love to see this adjusted by some alpha geek charter according to what Dr Singh is throwing down with  @caitlinlong in this talk. Not sure how one would calc the hidden liquidity so to speak. He's probably the only who could.

 I guess what dr dude is discussing might be qualified as “trapped liquidity” so maybe it doesn’t actually fit in the calc?
