You are right, 18 items is too short for a test. I might be testing more if i feel like it, not to test luck but to base it around how often you can get above +10.
The video was never meant to show anybody right or wrong but just a realistic reason to be skeptical about the fact what’s going on with all the high perfect upgraded items.
It’s on IMC to look in the logs what’s really going on… If it was me that had that +15 pefect GC legit, i wouldn’t worry because i know that i made it in a legit way.
Then again the brother from the other post is not very smart for making several +15 items in an era of all the exploits and expect to be not frown on…
