"numerous players" A few weeks ago you didn't know anyone that used CTE, now you know numerous players. That's a little funny. CTE aimers have no need to double check there aim with fractions.
I only personally know one guy who uses a pivot system... Shishkabob. But having sold a thousand books since February, I have plenty of players contacting me from around the world. A few right here on AZ that actually use CTE have mentioned in pm and email that they find my fractional method convenient for double-checking their CTE. No need to make that up....maybe they'll reply to prove you wrong, but I doubt it because they seem like reasonable people and not pot stirrers.
