Extreme Troyer Factor
(Full credit goes to Brad Troyer on all of this. And thanks to CTAC for this particular image) I really enjoy analyzing the numbers for sub 20fpe field target matches, and that typically entails using Brad's chart. A few days ago I realized how cool it would be to extend this out, in both...

You could even push the easy button and do it like this:
(Distance * 1.2)/Killzone size = ETR
This does make the shorter shots seems a little harder than they are, so maybe:
If distance > 50 - (Distance * 1.2)/Killzone size = ETR else (Distance)/Killzone size = ETR
(Distance * 1.2)/Killzone size = ETR

The original Troyer factor for sub20fpe field target is mostly distance/kill zone size but has a difficulty factor applied for targets beyond 45 yards. After consulting with Brad Troyer I concluded that the Extreme Troyer needed two difficulty factors.
So....the Extreme Troyer Factor chart in the link above is also mostly distance/kill zone size but has a difficulty factor applied for targets from 51-75 yards and then a higher difficulty factor for targets from 76-100 yards.

As discussed above, I modified the standard charts with the formulas in the post referenced above and use this to set up our matches.
