Charlie,

I think the columns are shifted to the left by one because the 40 meter 
version is speculative (i.e. there is no actual model number assigned). 
Just by rough scaling, it wouldn't make sense for the 40 meter version 
to have a 40ft turning radius. A 40 meter version with a 19ft turning 
radius and weight of 40 lbs is a much more sensible extrapolation when 
you look at the 30 meter and 20 meter specs.
