Perfect Repair

“	either attempt a one-point repair or attempt a Perfect Repair, which are consecutive one-point repairs until the item is at full durability.	„

I think it is very clear from this part of the article that a perfect repair is multiple one-point repairs. Further down, there's even a bullet point that says:

“	If a failure occurs in the middle of a perfect repair, the rest of the repair will be done at the non-blessed success rate.	„

This makes it even clearer that a repair can fail in the middle of a perfect repair. I don't see what the issue is with Yinato removing the extra bullet.
