Wow, so it is a recurrent dislocation/subluxation. It begs to ask the question..."To reconstruct or not?"....

I would say that the general consensus is that the more times you sublux/dislocate, the more you sublux/dislocate. Having an Wikipedia reference-linkMRI to ascertain the level of damage to the labrum and integrity of the capsule/articular alignment and whether there is a case for repair. From a rehabilitation standpoint you really need to test the arm in the more vulnerable positions with similar forces to what you will experience in your sport. Passive range and therband are unlikely to be close enough to the real thing to say with confidence that you are ready. That said as least you are working in the right direction.

Let us know how you get on
