I confess I am curious about this use of "automatic". To me, if a raise is automatic, then passing is either never considered or at the least never selected. It's therefore not an LA.
Of course, it is possible for pass NOT to be an LA without the raise being automatic: the choice could be between a raise to game and a slam try, for example.
Formally:
Raise automatic implies pass not an LA.
Pass not an LA does not imply raise automatic.
The test for the automatic nature of the raise is sufficient, but not necessary, for pass not to be an LA.
Sure, but all you are doing is complicating matters unnecessarily. It is perfectly possible for a raise not to be automatic, but to be so likely that pass is not an LA. Sure, if a raise is automatic, pass is not an LA, but if a raise is not automatic you have no idea whether pass is an LA or not, so now you have to go about finding our whether pass is an LA having wasted time and effort.

You are right in theory, but I agree with CamHenry: in this case, don't these questions come to the same thing?
If pass is a logical alternative, then the implication is that raising is not automatic.
If pass is not a logical alternative, then the implication is that raising is automatic.
Absolutely not.
If pass is not a logical alternative, then the implication is that raising is either automatic or not. Very helpful.
Suppose you poll ten people. Nine raise and do not consider pass, one passes. Now pass is not an LA, and a raise is not automatic.
You have a standard for UI based on an LA, so you have to determine LAs. What on earth is the point of using a different standard that may come to a different answer when UI is not based on that different standard?
