I saw Mark's point about 1/250 but I couldn't locate the statement from the organizers. Larry says a number of speakers offered to swap their double sessions for more female speakers, but would those new speakers be the single applicant or other speakers who hadn't applied.
Regardless, the conference organizers are at least partially responsible for lack of diverse applicants if their speakers were able to find candidates on short notice.
