Strange results in carding need someone advanced to tell me where is the mistake

[Bismarck]

The strange thing is with same method using bin ****** same site just different cards and profiles in the antidetect browser last week i manage to success now i got declined few times in a row
I have got different results... Could be the validity of the cards in ProZone Beanum is lower than 90% because few cards in a row ....(on the second card my proxy was with slow ping network that could burn it I guess)
but I dont check them, now i think to check them before start real shit...
Have you been checking cards with WIKI-donation do donation like 3$ before start real shit
Is it a good way to check without burn the card
Before carding i am checking IP froudscore and ports also is close to the CardHolder address
Only thing that i dont check is the IP of cardholder and mine to start with same numbers like (102.)I think its the validity of the cards
Please advanced users to help me I offer and monero for serious advanced teachers and advanced cashout methods?
Thanks!

My advice if you test cards on donation site just wait an hour or two before using card on your actual work if not then use card on your actual work first.
Secondly check if ip date and time matches with your system , ip leak and same state ip is a must .
thirdly with most big shop you must build browsing session as a real person and check store policy if the ship to only billing or to different address
Lastly , If you do not trust your bin always try low amount
