also, your pronation is not because of the ssc. it's because you have a decent swing path and your arm is relatively loose. in that case your arm has no choice but to pronate. You have almost no ssc going on. close to zero because of your takeback and setup just before going forward. couple of issues there. I could explain if you want me to.
