That's what I was trying to explain in post#9.
If there's something in that post you don't understand, I'll try to go a little deeper.

The point is, though, that there are ways to do it without the IFs. On the other hand, PBP is dreadfully inefficient, so it might be better to use the IFs anyway.
I completely disgree.
There are many ways to be inefficient with PBP, but PBP itself is not the bottleneck.
