Question about Forge and cube drafts

Hi, I have a 480 cards cube and wanted to draft it using Forge IA but have a doubt. Since my cube has 480 cards but the program seems to draft only using 7 IAs, I guess that only 360 cards are draftes each time. But, these cards are always the same ones or are randomly selected each draft session?
Knowing this I can decide to cut my Forge cube to 360 cards or not.
Thanks a lot for your answers and have a great day.
