Historically women have comprised about 10-12% of both attempts and successes on the Bob Graham Round. Someone, somewhere (might have been Graham) corrected my assumption that this was about the same percentage as female FRA membership when it's actually closer to 25% (even that may be out of date).

This year women comprise 20% , actual numbers are 17/83, of successful rounds (it was at 25% about halfway through the season). Not sure why the sudden rise and obviously I've no idea whether it's a one-off or the start of a long term trend.
