Trying to reduce the number of files so here's the first part. The info on the tags is true to the best of my knowledge although I did have to do some coordinate conversions which may have gone wrong so it's always worth double checking the info with the report.
Personally in the little practical investigation I managed, I never got the results of the report.
I'm also surprised those trenches at SB among the trees were never dug as the results from them are quite good.
