Thanks. You just made my point. You chose what you did because of what YOU wanted. And the geometry DID matter.
Now own it Like you said you would. You used a longer stroke (and lost R/S ratio at the same time) because of what would CHANGE if you used a shorter stroke (and consequently higher R/S ratio). So yes, geometry matters.
It just took all this bullshit for you to argue around to get to the point I knew you would.
Own it. Geometry matters.
