Which side to keep PB on?

What would be ideal?

I noticed that some runs keep it on the left and others keep it on the right. With the aggro glitch I supposed it didn't matter since it would hardly do anything to begin with...but now that its fixed...

I heard that if the bean is on the right side it'll seduce? Any validation?

Keeping it on the right it will seduce + genesis.
Ideal is keeping it 4/5 to the right but not all the way I think.
