It was me who had the training from Korean coach and made that comment.
What a shot sequence does for me is it enpowers me to commit to the shot but to also abort the shot at any time when it doesn't feel right, the aim is just one step in the shot sequence, no more or less important than any other step,I find this keeps everything together and doesn't let the aim interurpt my form (normally back tension).
One training exercise I did last week and I found this helped my form and groups, once I'm settled into aim I start the expansion counting 1000,2000,3000, the release happens somewhere around 2000 (still subconscious suprize) but the back tension feeling has continued to 3000, I will only use it during training but hope it will be ingrained into my subconscious shot sequence, I discoverd a weakness in my form of stopping back tension to soon after release (more so in pressure situations)and I'm finding this technique a great help.
Following a shot sequence starts off on a conscious level but because it's so complex were hoping to transfer most of those more complex movements to the subconscious and only become consciously aware of the sequence when things dont feel right.
