Another problem is that that BB comparison is not based on the latest updated version of Okun's analysis. Also, there's no data available on the armor quality of the Richelieu either - and I have the suspicion that French FH armor was at least as good as the British one, or even comparable to the Italian one.
I base this suspicion that Italy and France did get Austrian dreadnoughts as reparations, and they had Witkovitz armor (about as good as British FH) as a starting point.
