Does Height Matter Pt 2?

I want to make this process as scientific as possible so after feedback from another user I have rerun the testing with a LW. Part 1 can be found here.

Hypothesis and method are the same as part 1.

Results and Analysis

Source Data (Excel)

Once again the data doesn't vary with Skytrak height. However, with a high launching club and the Skytrak in a low position the cameras must miss some/all of the ball flight. Of my 10 test shots the only one which registered was a thin. It failed to detect all other shots.

When I originally tested with a 7 iron I was looking for variance in the data produced (e.g. launch angle, spin etc) and I did not see this at any stage. Nor do I see evidence of this in the LW data.

I think based on this it is possible to predict that a low launching club (e.g. 3W) could suffer non-reads if the Skytrak was too high. To run this test I need to be brave enough to swing a 3W in my garage!

Guidance:
Based on the above and previous experiment I think it is possible to make the following recommendations:

1. If you suffer non-reads with a lofted club the Skytrak is probably too low. Raise the Skytrak by 25mm and try again.
2. If you suffer non-reads with a low-lofted club the Skytrak is probably too high. Lower the Skytrak by 25mm and try again.

Does height matter?

I have seen a few comments about getting the Skytrak at exactly the same height as the ball for accurate readings so I decided to test it.

Hypothesis
Varying the height of the Skytrak relative to the ball will alter the readings produced.

Method
Hit 10 shots with the Skytrak approximately level with the mat.
Hit 10 shots with the Skytrak approximately 30mm above the mat.
Hit 10 shots with the Skytrak approximately 30mm below the mat.

The Skytrak protective case was used.

Results and Analysis

It looks to me like there is little difference in the results with a fairly significant deviation in the height of the Skytrak (60mm high-low).
