Ok, I'll explain what I mean better:

By looking at certain bits of data, they attempted to find these 'cigar butt' companies - Graham more than Buffett. The way they did that was to comb through a lot of data in a way that can now be done by a computer extremely quickly. So perhaps 'quant' is wrong... shall we say 'data driven'? Of course that's not all Buffet did/does, but it just struck me as an edge that he had then that he couldn't have now.
