Any references for Cunliffe on Maiden's Castle ? I only know the original publications (I think M. Wheeler ?)

This was spotted in the following thread: http://slinging.org/forum/YaBB.pl?num=1237975848/11#11
and there were some responses on that thread.

Mrboss, not everyone is interested only in throwing long distances. In the context of their experiments they would have been more interested in the distance people could comfortably throw.

It would not have been that dangerous standing downrange provided they kept their eyes open. Peruvians throw pretty big rocks and they were probably easily spotted, and could easily be dodged.

I think the results they obtained were interesting, and they did quote their 'raw data' which is rare, but I think their data reduction led to rather pessimistic conclusions about the ranges which might have been common in earlier times.

They seem like smart college students, but they also seem to have a death wish. Heres a quote:  "members of the crew stood in
the area where the slingstone would impact. Though dangerous, it
is the only way to accurately observe the impact point of the
projectile". -  

Now thats one of the most dumbest things ive read in my life, theres no way you can see a stone from a sling coming toward you, and they would have most likely died.
