I think that someone said an equal spread of each would be a test and I'm inclined to agree. Whilst the ability to flatten standers does give you confidence on the course it's still possible to do well in FT without mastering them. I speak from experience there where I've hit all my sitters and kneelers yet won on 50% standers.
