Here’s how the eleven countries that upgraded from O to P membership in the months (and often just days) before the OOXML voting period closed on OOXML, and also whether or not they voted in the more recent ballot (all data is from Rick's analysis of the voting record):
-- Upgrades that voted to adopt OOXML and didn't vote later: 7 - (Côte d’Ivoire, Cyprus, Lebanon, Malta, Pakistan, Turkey, Venezuela)
-- Upgrades that abstained on OOXML and didn't vote later: 1 - (Trinidad and Tobago)
-- Upgrades that voted against OOXML and didn't vote later: 0
