This analogy is FAIL.
It would make sense if you were going into a poker room where you KNOW everyone is at the same skill level, same bankroll, and same end goals. That's not the case with a PO freeroll. Lets take your example and make it a video booth that plays random movies everyday....
That's what you get with a freeroll. Sometimes you get really solid play at a table, then you get moved and BAM ur stuck between GregorSamsa and DrJack, with Rivdee sitting across the table licking his chops knowing that there are two DONKS and a guy (you, for example

) who gets way tooooo tilted by the bad play of others just waiting to be had.
What you call "Bingo" Players I call potential easy double-ups.
