I sended a lot of hands to the support in August.
It was not autoimport, just import from folder. I imported the hands directly from Winamax (I asked the support, to resend me HH-s), and I tried with exported hands from PT4 too.
The end result is that always missing 10-11% of the hands. The intresting thing is always different hands are missing (H2N said after the import that hands are duplicated). I made a lot of databases to import the same 3K hand to each databases (I think a had 14 DB in the end), but always different hands are duplicated.
So I cant use the H2N on Winamax becouse the HUD shows me fake statistics when important hands are missing.
