I was gonna post last night after I read this and then I passed out after paragraph 3, but to sum up my opinion, I do understand where you are going with this Dave242, but you are arguing semantics IMO.
Here is a good definition of OAT I found by Bradley Walker.
"Of axis torque
this is the condition that results from the hand not perfectly
tracking around the nose
within the plane of the disc into the extremely powerful snap. Think of the top if you wrapped the string
askew at some odd angle. The harder the string is pulled the more wobble will be induced."
IMO if I you really wanted a clearer term than OAT......you could call it OIAT......(Off Ideal Axis Torque), but IMO that just doesn't sound as cool as "OAT".
PS. Dave if you haven't delved into technique yet, I would strongly recommend starting here, then after you read this "summary if you will" you may be able to coexist with the word OAT.
....lots of good stuff in there
