I'm going to butt in here a little bit.
Not necessarily more consistent than with other pathologies. Could be the labrum, or other anterior structures like the capsule, could be supraspinatus or referred pain from the AC joint due to the compression (or other structures referring). Could even be radicular. You'd have to have more information and do tests, eventhough the sensitivity, specificity and overall diagnostic value on most are piss poor.
The short head of the bisceps brachii inserts at the processus coracoideus, as I'm sure you know, and if it's an enthesopathy of the short head then it might as well be the pec minor that's causing the issue. The symptomatology is also different from a tendinopathy of the long head. Again, while palpating the AC or creating compression certainly would create known pain locally at the AC joint, referred pain from both the AC and other structures can be felt anteriorly near the front delt, or at various other places at the delt, or the upper part of the humerus. I agree with you that most rehabilitation is pretty cookie cutter regarding anterior glenohumeral issues though (if that's what it is).
Sorry to be brash but with giving diagnostic advice over the internet it's important to be sharp.
In the end TS only had pain once, came to Sherdog, then the pain went away. Pretty much making a mountain out of a molehill. Or so it seems.
