Hi Elena,

❝ This is our first experience in conducting such studies, so we are quite excited.

Keep in mind that it might also be the first experience for the experts of the agencies you are aiming at. Possibly they have heard about the skeptic attitudes of European assessors towards ‘Method C’. Consider ‘Method B’ instead. See the end of this post for a comparison of power. What will it help to have (maybe) two subject less in the second stage and a study which is not accepted? I warned you.
