I have both the Mantis X and the iTarget
The Mantis X only tells you which direction and how much the gun was moving as you pulled the trigger. The iTarget shows whether you actually had the barrel lined up with the target when the firing pin hit the laser bullet, but not whether you were still or sweeping thru the hit area. Its possible to be dead on with one and wildly miss with the other. If you can bring them both together on center, you are doing very well. The $5,000+ target practice devices that the Olympic trainers use do both. If I recall, the Russian device sometimes sells for around $3,000 used.
When shooting one handed, the only important thing to do with your other hand is - the same thing every time. Many competitive shooters hook a thumb or finger on a belt loop, pocket, button or something to give them consistency. Find what works best for you and do the same thing EVERY TIME.
Tilting your head slightly down is OK, but side to side level across the ears is extremely important. Your brain understands the target presentation much better when level across the ears. If you look at pics of shooters that made their Olympic Teams (rifle and pistol), you will see this consistently - because it is what works.
