Where is the line between normal and Winged Scapula?

[Fiskevatten]

Did exactly as instructed and got great contact with the middle part, lower needs a little more pushing.
Felt like I hit a ton of smaller suckers.
Any idea how often I should hit it since it's clearly under-developed? Like a eod as a start or finisher around my regular workout?

I'd start with 3x per week
