Vinnie- I guess we'll see how it works out in the long run. As I've stated from a lot of experience with two stroke engines, too much oil is as bad as too little for different reasons. I am not telling anyone they SHOULD run 30-40 to 1, but I personally would.
These engines (also as stated previously) come with instructions written by the manufacture (Chinese) and the type of oil they use would probably be O.K. at 20-1 just to keep enough lubricant in the fuel. (I can go into more detail here if you wish, but suffice to say the oil "over there" is really, really bad.)
However, modern made in the good 'ol U.S. of A. oil should be more than sufficient at 36 to 1 or 40 to 1. Case in point- we used to run our big two stroke ultralight aircraft engines at 24 or 36 to 1, now we run the very same engines at 40 or 50 to 1, the oil being the only difference.
For those of you that will still want to run 20 to 1 mixtures, I would suggest you keep a close eye on carbon build up in the exhaust, rings and piston dome and clean accordingly. I'd pull the pipe and or head every 20 hours and have a look. At least check the plug (not the best indicator) every couple of weeks and see what it looks like.
I'm guessing these engines should run about 250 hours before they need a rebuild? Maybe less based on the technology (or lack thereof).
