I knew that but I'm about place of letter
i (before or after number) is important: 25i means 25 full-height frames are get from 50 interlaced (half-height i50) frames.

Commonly you're right but in case of static it's equal.
Btw high quality double framerate deinterlacers (i.e. Yadif) gives enough video quality for not too fast moving to say i50=p50=50p - in case of progressive video place of
p doesn't important.
