The Study doesn't account for actual wind capacity factor, because it uses data for very old machines. Reality shows much higher capacity factors, as more modern machines enter the UK, as demonstrated throughout the EU.

O&M costs, currently quantifiable, are low, and change every equation.  A BNEF study privately available shows O&M costs dropping from 30,900€ to 19,200€ per megawatt capacity over the past four years.
