Panda Cloud AV offline efficacy?

Does anyone know how effective Panda Cloud AV is without an internet connection? I know the virus definitions are cached for such situations; but what about rules for heuristics/behavioral analysis? Is just the performance of the AV impacted when offline, or does the efficacy of the heuristics and whatnot also drop? Has anyone done tests on this?

Edit: Argh, looks like I posted this in the wrong forum. Can someone move it?

 

Thanks.

 

you get i believe 71% of the database from online. but online is the best. but Pbust will have to give more input on it. im not really sure.
