Covering Circle Radius versus Extreme Spread  should be pretty good.

Projectile Dispersion Classifications  getting close...
Extreme Spread * measure
Figure of Merit * measure
Leslie 1993  notion ok, disagree with content on page.
Measuring Precision  this is fairly solid.
Mean Radius * measure
Sighting a Weapon ** needs work
Stringing seems mostly ok. Fuzzy on how to handle inter/exterior ballastics.
What is ρ in the Bivariate Normal distribution? think this pretty good.

Suppose that Xk has the gamma distribution with shape parameter k∈(0,∞) and fixed scale parameter b∈(0,∞). Then the distribution of the standardized variable below converges to the standard normal distribution as k→∞:
\(Z_k = \frac{X_k−kb}{b\sqrt{k}}\)

"The difference between theory and practice is larger in practice than in theory."
In theory there is no difference between theory and practice. But, in practice, there is.
sighting shot distribution
The Mean Radius is the average distance over all shots to the groups center.
Given 

Assumptions 

Data Pretreatment  Shot impact positions converted from Cartesian Coordinates (h, v) to Polar Coordinates \((r,\theta)\)

master ref page
I like the structure of this wiki page. You can look at the "groups of papers" then jump to a specific paper and use the browser back button to go back to the group.
Could we make this the "master" reference page?
(1) Move references to top of page (2) put TOC that floats to right (3) Have level 1 headings for various topics (eg CEP Literature, EEP Literature, ES, Rayleigh Model, Hoyt Model) (4) Each level 1 heading would have various "groups" of papers. (5) From some paper that we want to discuss create an off page link for that paper. (eg comments on "prior Art" page
how I'd redo references so as to provide some that was "linkable" and could be "named"
So Blischke_Halpin_1966 could be name of wiki page and a "named" link within the page. thus reference in a wiki page would be something like:
: yada yada yada (Blischke_Halpin_1966) yada yada yada
the link would jump to the "master" page of references to that entry.
