does 24f lose vertical resolution?
and if so why?
isn't it basically the same as 24p does that lose resolution?

In one theory, up to 50%. In practice, well.... people measured it to loose just 10-12% ; most people can't see any resolution drop compared to interlaced.

Nobody wanted to answer specifically, because really, nobody knows for sure.
