Thank you for the update and continued communication Jeff. It's truly appreciated.

Also glad to hear the multivalve factor is being discussed further. I agree that ideally it doesn't matter what the default is if the group gets the gain numbers right, the reality is not as simple otherwise we wouldn't have a default at all.

If it's decided that a multivalve engine makes more than a 2 valve, should there be a difference between 3 valve and 4 valve engines?
