Luxify checker

[labrosf]

Hi, so i started using a random checker from 2 years ago i found here for disney plus, it was fast enough and it got 14 hits in 7k combos, then i used luxify
on the same list to see the difference, it sure as hell was faster but after 14k combos it got 3 accounts and none were the same as the first checker sicne they were all below on the combo list.
Any idea what might be happening?
