Incorrect Archiving, QGD Game

This could be a morning coffee issue, but here it goes.

I'm somewhat new to exploring archived games in general, more so with chess.com's Game Explorer.  But I was running through a few QGD variations, and after 1.d4 d5 2.c4 e6 3.Nc3 Bb4 4.Qa4 Nc6 5.Nf3 Bd7, two master games were offered.

The first move option, 6. cxd5, refers to the game Bodini - Biggi A, and is scored 1-0.

The second move option, 6. Qb3, refers to the game Khmelnitsky Igor N - Stripunksi Alexander, and is scored 1/2 - 1/2.

The second game is archived correctly, ending in a perpetual draw.

However, the first game is archived incorrectly, ending in black checkmating white.

So, I suppose I was wondering how often things like this happen, and how it affects the usefulness of chess.com's Game Explorer--how it affects, for starters, how win, draw, and loss totals are displayed. 

Thanks!

I'm sure it is not the only mistake in the whole database.

I don't believe I've ever seen anything on where chess.com gets its database files. 

I'm sure you're right - it would be a strange chance if I landed on the one odd duck!

I have leafed through a few books in the past but never sat down to study the game until recently.  Now I'm discovering that I like the idea of the Game Explorer, and I'm trying to figure out the best way to use it.

 I opened the thread, not because I wanted to be a nit, but rather as a gauge, to see how many other users use Game Explorer, how those users apply it to help their game, and whether or not the "crowd sourcing" W/L/D totals were useful. 

You have to be a little careful with the win/loss %.  Sometimes a line has been refuted but the numbers are still high because the refutation is recent.  Not something I worry about a lot at my level.  Unfortunately, once you start checking DBs, it's hard to stop.  In correspondence chess (online, daily, whatever...), you can drive yourself a little mad trying to figure out your next move by how popular it is in the DBs.  And of course if you follow the most popular line without knowing why the moves were played, you can easily find yourself in big trouble as soon as your opponent leaves book.  DBs are terrific tools of course when used wisely.

I really just starting use the DB.  In general, I play out several scenarios for both sides until one or two master's games appear, then I play through those to see if they make sense to me.  Typically they don't, but so it goes.

I guess the win/loss %s seem to be the most confusing, maybe even the least useful thing to me.  At least, I haven't figured out how to make them work for me.
