Also probably why the guys' targets looked all over the place. If it was vertical stringing then that's what they were doing. Maybe you judged them too hastily.
That is a good explanation of the process in your article.
It was not vertical stringing and clusters on the targets. Shots deviated quite a bit both vertically and horizontally with no apparent clusters. The horizontal deviation appeared to be just as great as the vertical. I do not believe that any discernible pattern was on their targets, taken either individually or aggregated for each shooter. In other words these good fellows just banged away and hit the targets all over the place. It is hard to get any meaningful results out of bad testing and when your grouping is the size and shape of a ball cap you have problems other than barrel harmonics. Some combination of shooter and shooting gear was not quite up to the task.
The ladder testing process can be useful but only if the shooting is well executed.
Maybe they should buy a proper rest and bags, get some more real shooting experience, listen more and talk less, and perhaps read your article.
