Interesting, Art. I took the data and graphed some of it. You would expect the hit percentage to decrease as the Troyer goes up, and it generally does:
But there's great variability. The trendline is questionable given the wide variation in some of the lanes. If we take the lanes listed as affected by wind out of the equation, you get a pretty good look at the relationship we want from the Troyer measurement:
But if we look at just the lanes impacted more by wind, we lose much of that relationship. I'm not sure I would have even drawn a downward trendline here, given the variability in the data.
There is still a generally decreasing hit % with increasing Troyer, but not much, and there's significant deviation from that.
So, what's the point of all this? Well, if we are trying to use a Troyer calculation for Extreme Field Target courses in different locations so that we can compare and somewhat equalize their difficulty in terms of kill zone sizes, placements, etc.,
At least as far as this event in the 5 instances it was shot with an average of ~23 shooters each time,
1) while the Troyer calculation for extreme field target distances holds, it is much more accurate in the "non-wind" lanes, and far less predictive in the lanes affected by wind. If we are trying to standardize the Troyer measurement for courses in different geographies and locations, this could mean that a Troyer calculation for an Extreme Field Target course that was windy throughout many lanes would produce a Troyer factor that was not useful to compare to other less windy courses.
2) Based on this (limited) data, perhaps the Troyer for Extreme Field Target distances needs to account somewhat more for wind given it's increased effects on pellets shot at > 55 yds.
