Maggie is 100%, often even if sick (she'll wake me up to go out if she's sick, even for vomit). She's gone up to 16 hours for urine and 32 for poop (while we were working on teaching a potty cue intensively).
Ziva is 100% up to about 10-11 hours (my longest day at work), but she sometimes forgets to fully empty outside so I have to make sure she goes before long absences.
Kes appears fully housetrained, but I've not tested it - he goes out every 2-3 hours if loose in the house, every 4-6 if tethered, and is good for up to 11 if crated (that was an exceptionally looong day at work - only happened once). I guess he's well cratetrained but probably not 100% housetrained.
