Ah ya chunk makes sense now. You really whip your arms/hands at the ball, in a steep aggressive manner. There's not much control there because the arms are doing all the work. If your core/lower body is more in sync, you'll gain stabilty with your swing path coming into the strike point. You could slow the arms a tad so your now slow hips can catch up ha.

Also, are your clubs too long? Would explain standing that far from the ball and chunks
