Greenblatt’s funds performance, e.g. value fund, aren’t eye-popping either

Philosophical question: what defines a ‘quant method’?
Buffet’s early returns were certainly great.
But his later returns, as the fund grew larger were less great, generating much debate on the BRK board of whether it beat the S&P (a start/end point dependent question).
Is WEB using a ‘quant method’?
He’s certainly thinking, i.e. presumably he’s not throwing darts at a dartboard.
But we apparently don’t know, and perhaps he doesn’t know, how to reduce his thoughts to a relatively simple algorithm (I qualified that sentence because presumably one could cook up something complicated that matched his returns year for year, but odds are it wouldn’t extrapolate)
