I have seen gear prints from FP, they are definitely an English unit company, at least when it comes to gear pitch. I would be shocked if they switched back and forth between metric and English.
In any case, I am confident that this year's first stage is 32 DP 20 Degree Pressure angle (which is close to a metric module of 0.8 but not quite 32DP =0.79375 module). It may run with a .8 module gear, but it will never be happy about it ;-)
