I keep refraining from answering, because I realized that it wouldn't make sense to continue this conversation, but I can't help it.
What "multiple factors" are you talking about? Perry's hat who has the same bonus as Cortina's tie, works the same way, exactly as I explained above, it receives a 10% fixed value, it is not rounded. (0.5+10% from 0.5 it's 0.55 by the way). Your example is not related to the problem I highlighted because I explained above how it works. When it comes to speed it's different, but how and why? You didn't answer me, you quoted the same meaningless answer in the current context. What multiple factors are you talking about?
