Trigger control for SD shooting

[Zodiac595]

So, got this on an email from gun digest.
now I haven't done a SD class yet, and I take in from what you guys say and what YouTube shows and then things like this, now, the principle. Looks correct if I think about it, but what say the instructors on here.

thanx

Thanks for sharing. Let's wait and see what our GS instructors have to say but sounds fair to me.
