urgency='low' testing propogation only 5 days for gtk+2.0?

[Justin Pryzby <justinpryzby@users.sourceforge.net>]

It is my understanding that an urgency='low' upload defines a 10 day
delay in testing propogation, unless overridden by hints.

However, yesterday's gtk+2.0 upload indications only a 5 day delay.
Why?
