What I mean is the numbers that RWD are getting from these long trenches aren't as good as what they averaged from the series of small trenches.
The single AMN short trench is double that of the RWD long trenches.
What I am suggesting is that the short trench studies might not be completely reliable. Alternatively it might just be the current location chosen by RWD or perhaps RWD wasn't so rigorous about steady state in the short trench studies ( I would need to go back and check).
So if the short trench studies aren't replicated, more trench may be necessary. Make sense?
