Almost there, one last question. If you lined up to the target lets say square to the target line and made a swing and the next swing 1° open and both swings were identical, would it read as identical swings or would the 1° open alignment show up as a different swing? My biggest concern is that aligning up exactly the same for each shot is very difficult (when were talking to the tenth degree) and that if you don't it might be mistaken as a different swing.
The radar doesn't care where you line up or how you align yourself to the target line. It is only interested in what your club is doing in relation to the target you selected. No different in how you hit shots on the course. Pick your target, align yourself how you need to, then swing. You will have a range for your good shots (shots that are acceptable to you), and a range for your bad shots. If you hit 10 balls inside a tight circle, they all won't have the same numbers but they'll be within a tight corresponding range. The opposite would also be true.
On the course, you hole your eight iron from 150... that shot would have a specific set of numbers. On the next hole, you have the same shot and feel like you made the same swing, only this time it is 5 yards to the right... that shot would have a specific set of numbers too. Both shots you intended to hit right at the flag, one you did, one you didn't. The radar would tell you why the two shots were different in relation to the target, not if the swings were identical to two separate targets (where the second ball ended up).
Something like the Ping putting app would be an example of a device that doesn't record its data in relation to a constant target. You make a stroke, it tells you what your putter did on the stroke in relation to the direction you sent it. You might have missed the putt by 3 feet, but still score "zeroed" numbers. TM and FS are tied to a designated target, you wouldn't have two sets of identical numbers if the ball went two different directions. I like/use the Ping app, but I prefer the target based systems.
