Nice attempt at a "scientific" approach.
The only thing I used on my DR650s' (s- as I've owned a 91 and 97) was spray on silicone. Worked great as a cleaner and lube and since the o-rings are of a silicone compound it just always made sense to not mix compounds to me.
I'd clean/lube with the stuff every 1,000 miles and routinely get between 15 and 20,000 miles per chain/sprocket combo. Not bad factoring in all the water crossings and river grit.
Shame I didn't find what I was looking for here in regards to my chain wear search, though!
Good Job but, there's just sooo many variables to consider.
