Some people got interested in the ratio of approved standards vs. rejected standards of the ECMA. This is particularly due to the fact that ECMA proposals have up to now been taken on fast-track adoption by ISO. On the other hand, it has been argued a lot that ECMA is a pay-by-standard organization.
In fact, ECMA 376 «Office Open XML» is the 376th standard proposal handed in at ECMA, and the 376th standard. So apparently, the ratio is 100% – every single standard proposed at ECMA has been adapted.
