No it does make sense Joe.
The thing is, we're used to doing short chips from the greenside fringe, and for most, they're also just used to hitting nothing but full swings.
These half and 3/4 shots probably need to be practiced more than full swings, particularly if your course management leaves you in that nasty 30-40m range often.
One thought is key though I reckon to success with these shots, and that's, you want your thru swing to be longer than your backswing.
A lot of people will take a bigger backswing than they need (cause they're used to hitting nothing but full swings), and then they decelerate thru impact, and finish with a short follow thru, when the exact opposite is what is required, in my opinion.
Setting up for these shots is also key, in promoting confidence. You want your weight on your front foot, and you want to keep it there throughout your swing. This will give you confidence that you are going to hit down and thru the ball with a descending blow, and not blade it or chunk it.
So no weight transfer at all, shortish backswing, and just accelerate thru the ball, and you should soon be able to dial those shots in with practice. I'd practice hitting that same distance with different clubs, different ball positions, face angles, etc, cause that's how we learn and add more shots to our arsenal.
Just my thoughts of course, but hope it helps buddy ....
