Bart Hanson didn't consider it a solution from a solver. He considered it a live, low-stakes NL exploit.
I don't really have any data on how accurate and useful that advice is, though.
It's fine as an exploitative play, but it's silly to try to calculate EV changes based on numbers that Bart pulled out of his ass.
