Andres,

I browsed "ERROR DISTRIBUTIONS AND ACCURACY MEASURES IN NAVIGATION: AN OVERVIEW". Thanks for sending; at 85 pages, it's quite a tome. I marvel at the author's obsession and guest discussion about measurement but have to ask - Who is the audience for this work? Oddly enough, I found almost no mention of sight data as we deal with when shooting celestial bodies - time/Hs or Ho. The results of various statistical methods do not talk about how observers can take advantage of these techniques.

Another consideration is how could these techniques be implements on the kind of field equipment most navigators have? Certainly smartphone apps today offer amazing functionality but to inplement these techniques would require programming and built in libraries. Not your average navigators kit.

In general, I feel that most of the methods discussed - after the basic standard distributions, r and r^2 etc. - are far beyond what navigators might understand and be willing to do.

So, I guess my question remains - what simple things analysis of sight data can one do to improve their 'seeing' and 'measurement'?
