The 80% gas sands, is new.
I wonder if it that = 80% chance of gas.
In the CUE preso for Caterina, they have 80% chance of gas.
I have not been able to find out if chance of gas is different to COS.
I think COS is commercial success, and chance of gas is hydro carbines.
If this is correct, then this explains the new 80% of gas in the new preso.
I would love to be enlightened.
