I find this credit extremely subjective. Or maybe we don't quite understand it... Our landscape architects have a hardtime in assuming what is the baseline case for "conventional landscape practices". Is there any sort of more accurate criteria to determine the baseline? How do you folks work on that?

And the other thing is that many projects here (Brazil) are manually irrigated with hose during the lifetime of the project. However the reference guide doesn't provide the efficiency for hose irrigation only for sprinklers and drip. So what's the efficiency to assumefor our hose irrigation? Ive submitted this question a few times before in this forum but no responses at all...

Any thought?
