Hi John

Thanks for publishing that. In low ceiling sites a number of us are using P/D ratios of around 1.6 as a bottom pitch setting and these are increased by both flare and torque. Is there any data which suggests that efficiency continues to improve as P/D continues to increase beyond 1.6 or is that broadly the peak of the effect?

Best Wishes
