George, All of your deductions are 100% correct. We build many 4.00 stroke Clevelands with no issues on oil consumption. Ring seal is the key to making power. Next we can work on cylinder loading theories and how to make it easier on thin cylindered engines. If there are any topics like this that maybe I can shed some light on , send me some suggestions as I'm thinking of adding a tech page to our website for good discussion topics. I have no problem answering questions like this.
