I suspect they will not provide this information. If you collect stats, however, you can achieve a very good approximation. Of course, the part about being based on level you could only tell over time.

I wish you the best, but don't expect the answer you're looking for.

i can give you the aproximates
1. = 1/100 +/- 5% drops being jewelry mark food armor wepons schemes grey/green quality if you got a grey wepon you got a drop if you got a grey jewelry item it counts as a drop you get a scheme you got a drop green quality item drops double during insigina battles lvl relation to drop 1/1 100% monster 1 lvl lower 80% 2-5 50% 6or more .1% lvl higher 101% 2lvlshigher 102% 30 higher 115%

2. tracking monsters = your lvl or higher 1/20 lower lvl ythen you 1/40 more then 5 lvls lower then you 1/500

all approxiamates based on observation
