Thanks for posting that..as much as anything because it prompted me to get my m’sand my u’s sorted out in my earlier post
I was typically picking up about 220 uSv a month , mixture of routes, when I did my logging, flying about 65-70 hours a month (those were the days).
If the high altitudes still bug people it is worth running dummy sectors with the same profiles, e.g. east/west high latitude vs. North south through the likes of CARI to see where the problems really lie and why “capping” levels down near the equator is almost pointless....
