Otherwise the office staff are working with flawed data, and no ammount of fiddling and tweaking will sort it.
I agree heartilly, it would be great if all context sheets had a measure of the excavators confidence of their results on there as a rough statement of errors.
Alternatively I try and look at every section on a site (not always possible on a pipeline though) as its being dug and ask the digger how confident they are. In that way at least you get a bit more information to help in post-ex when things don't add up.
It's funny how its often easier to see some relationships on first glance at a clean section, relationships that the digger had missed, possible from being too close to the data?
