What my esteemed fellow jock i saying is of course the shovel scrape of the eval trench base. which Dino rightly points out can also be extended to sections...
Like Jack I would say it is dependant on teh soil morphology - and how 'visible' the layers are. It is I would guess a rule of thumb to say.. confirm you can see what is going on... before sitting back and reading a copy of the Guardian/FT/DAily Mail
I recently cleaned the base of a couple of eval trenches to be sure I knew that I was missing nothing. with confidence, I was sure I would 'see' anything that the machining got to.
Once again... experience will matter even more. no point sending out a newbie...
