Yes, it's multiplying by 1000, but it's written in the book as "NMN.80.418" so it was not clear. Hmm... i searched the string today and got different results, so now i'm not sure. Now it says NMN is the character's initials, 80 is the year he graduated high school, and .418 is his batting average. Go figure.

I think i made a typo yesterday and searched NMM by mistake. Ack!
