Can anyone confirm that black cat's saliva actually affects the enchantments on items?

I know that black cat's saliva affects the value of some stackable items like generators, the more saliva you have, the more generators you get when you wish for them.

But i dont see anything that affects the enchantments on items such as speed rings when you wish for them, as equipment like that is not a stackable item. So in other words, i dont think that having, say, 100 saliva will make the speed rings more powerful or anything like that.

I tried save scumming a bit and saw no difference at all in quality when i wished for speed rings, compared to 3 saliva and 14 saliva. I am still getting speed rings averaging 12 speed and low powered enchantments like +6 literacy.

Looking at the code, i can only see that some items like as a rod of wish or medals are affected by wish power (which i assume is based on saliva) while others like deeds are not (its always 1 deed). Im not sure if speed rings are affected.
