I use of Rest rank 3 doesn't bring my anywhere close to 29% endurance, usually I'm lucky if it gets me up to 21%. That's whether or not I'm actually fighting anything.
That hasn't been my experience. Perhaps the monk you're testing with does things different than the ones I play with, but outside of 2 minutes I see monk endurance completely disappear in most cases. While a full burn will only take around 40% of my endurance while stretching it into my best sustained over 5 or so minutes will drop me below 40% total. That's IF we don't already have a 5 minute combat timer, it's 8 minutes or more to regain endurance from a raid environment.
