What's the level of supraspinatus activation in planche?

Just recently, I believe that I had inflammation in the supraspinatus. Doesn't really hurt, now, besides a few extreme positions. However, I just tested my fingers back planche lean ability and shattered my old PR. Unreal! Does this make sense?

There's some RC activation in almost everything. Just for stabilization. Less in hands supinated position because humerus is rotated externally.

Some level of pain will inhibit strength work so not exactly abnormal...
