From the affix list I see this

So is this saying there is chance (however low it maybe) that the jewel gets BOTH the affixes AND the Tir craft 1-3% bonus meaning hypothetically like winning the lottery you could get a jewel with 13% MF perfect on all 3?
Or am I mistaken and it can only get one of the affixes for 1-5 maxing at 8. If that is the case how are the 10% jewels being crafted.
