"The five, 5 shot strings show a ratio of 1.91. If you look at the chart diagonally, with equal shots with equal groups, you see the same 1.91 ratio throughout the chart. For three, 3 shot groups, the ratio is 1.91."
Paul,
Interesting. I hadn't noticed that. Do you think it is more than just a quirk in how the numbers come out?
After reading your comment about the shooters who placed low having L/S ratios of over 3, I went back into the results for the IBS Nationals and checked he top five placers and the bottom five placers in several matches. In each match, the average L/S for the top five and the average for the bottom five were almost IDENTICAL and very near the expected 1.9.
However, the group aggregates in the bottom fives were nearly twice as large as the group aggregates of the top five shooters. Whether this was due to better tune, better equipment, better wind doping, or something else is unknown. This indicates that smaller groups, no matter the reason, do not result in lower L/S ratios -- at least for the groups in the IBS nationals. This is of course what the article found for widely different group sizes.
Average L/S ratios of several strings of groups over 3 are extremely rare and usually because of a disaster in one group in each string.
The only Super Shoot results I can find are only for aggregates. Can you send me a link to your source. Thanks.
