as i said is diferent when we are talking about to obtain 1 result (a great Standard deviation) than multiple reults:

Of course someone could get it at first try, but if that person need 9 items double melded, total trys result will be similar to another one.

So your comparation is wrong, u had to say, i needed 200 trys to get all my gear double melded. That guy that get weapon double melded at first, will have problems with another piece. Is not easy to get all your gear double melded.

Same go with 9 drops, someone will have the first with 1 hamlet, but to get the other 8, he will go close to the Mean.
