You need to look at the data.
They had 2 duds.
Re my comment about SO4, they only had two trenches, one was good the other not so good, statistically I might have been slightly unfair but at least they have provided raw data which I don't think AMN did.

Based on the 159 cubes per KM, which is obviously calculated based on all the data, then it works out at 8 cubes per hour per 50M.
I think SO4 had a 100M trench which gave approx 1L/sec. 1 x 60 x 60 = 3600 L/H = 3.6 cubes/ 100M = 1.8 cubes/50M

RWD reckons it needs 5OKM for 400 Ktpa, AMN reckons it needs 250KM for 370Ktpa.

The market is missing something here or I am banging on about something that isn't important???
