I have been using it and getting buys between 3-3.8. Once I get one, I take a break and if its a more expensive MP, I break for the day. It generally works out though. Dont get too many in a row also or youre done.
My internet jumped and I got one at 1.6, and didnt get frozen. o.o
Also, abing after 8PM NST allows for more variance in the times due to less people being on
