This definitely comes down to personal opinion. Does it feel how you want it to feel? Does it sound how you want it to feel?
Feels too mushy → too much lube
Feels to clacky → too little lube (or not enough lube in certain places)
feels to rattly → not enough lube on either the wire contact portions, or within the slider (therefore causing some possible rattle)
Based on that picture, it’s kind of hard to tell. It looks like it could be okay, but it also possibly looks like too much. I can’t really see the elbows of the wire since that’s also a pretty crucial part.
