say i have a stop loss vs a single opponent, we'll call this y. if i lose y buyins vs one opponent i quit them. i also have a stoploss on the day, we'll call this x. if i lose x buyins in a day, i quit for the day. x overrides y in some cases, because i can be x-1 buyins down for the day, sit with player z and lose 1 buyin, which doesnt equal y my stoploss for one single opponent, but it equals x my stoploss for the entire day. in this example i would quit said opponent before my single opponent stopless has been met, thus x overriding y.
I hope this is an accurate example of what jsnipes means because I in no way use this and may or may not know what I'm talking about.
