What does CPL mean when reviewing a game?

I've noticed there is a button named "cpl" under "Replay Mode" when importing a pgn file. There are two other buttons that show "Fast" and "Slow". I know what those mean, but what does CPL mean?

Centi pawn loss. the average 100th of a pawn value you lose per move. 100 ACPL means that the average amount of score ( in pawn terms) is 2 pawns per move

Thanks @puzzlesandpuzzles. Still don't know how that deals with the game being replayed at a certain speed.

Around here it generally means that you're listening to a bunch of other people spout authoritatively about it (when they're not really sure what it means either). ;)

@Stevelabours The CPL-mode when replaying a game means, the replay-speed changes with the change of the CPL of the next move. Or in other words, when someone made a blunder, the replay-speed slows down, when none of the opponents blunder, the pause to the next move is shorter.

@nooboss Thanks! That was helpful.
