Thanks for the feedback, askrafiki! I confess it took so many and many hours of improvement kkkk, both to assemble a truly good team and to deliver on time. I had to modify the project language several times and optimize various variables, but today, depending on the account (accounts with fewer cards are submitted in approximately 10 seconds, and accounts with more cards in about 40 seconds), we have a slack time in the 180-second window. My biggest challenge right now is seeing how the VPS behaves with many people using the bot to manage the queue and avoid the WO's.
