there are a few values published by developer,

"http://www.prode.com/en/hydrate.htm"

I have verified some of these points (ask Prode for the list),
with simplified model for hydrate formation pressure you may expect an error in the range 3-15% (depending from structure and temperature),
errors in hydrate formation temperature are in the range 1-2 K

the complex model is more accurate,

when adding methanol as inhibitor erros are about the same (with the specific parameters provided for CPA PR Cubic Plus Association or other models,
however I suggest to contact Prode for more accurate figures...
