Hob, it's definitely one helluva chuffing scary document. I've managed to get completion down to 20mins, but that was for a rock with 1 cup & not a lot other stuff in the vicinity. Generally, it's taking me about 30-45mins per rock.
Agree with you about the analysis, theres certainly a danger of wayward interpretation sneaking into it. I doubt very much there'll be consistency across the teams recording, even though we've gone through the same training. One group thought they'd found an additional 40 marked rocks to Beckensall & to be honest some were laughable.
I hope after the analysis, they just don't come out with a theory, "RA is located near settlements, cairns / burial grounds & water courses", because it won't add anything new.
