Marcus clearly threw a lot of spaghetti, seemingly pessimistic "it socks and won't get better" and then cherry picks confirmations, for the bits that stuck to the wall.

How about he indicates: 1. How he came to these conclusions (coin flip? Pessimism?) 2. How many predictions he missed. He's implying a very high rate of success, which is a big red flag of shenanigans for me.

This is little more than vague generalities and coin flipping with retroactive cherry picked "See?! I was right!" analysis.

A gypsy at a traveling circus serves up about the same.
