NL ring game buy in accumulation question. (Low content)

[TRWIII]

Im just starting to read up on NL ring games (already a fairly accomplished SNG and low limit ring player, but as a personal rule I dont play any new type of poker until I read at least one good book on it... have ciaffone's book on order.)

I was watching a few ring games last night while I was multitabling 2/4 limit on empire and saw something Ive never seen before. At a 25 NL ring game, there was a player who had accumulated over 40 buy ins (a touch over $1020). How often does that happen and how long would you suppose he had been sitting at the table? I watched him for most of an hour and I still wasnt sure whether he was that good, that lucky, or both.

Like I said, low content, just thought I'd share and see if this was more common than I'dve guessed or it was a unique occurrence.
