There probably is, actually. Like years ago when FP4 was rated at 64 then magically went up to 125 (so I've heard, I think it was before I was born).
Calling something '25' may actually have marketing benefit, even if it's a 50 that looks good pulled down a stop. I know I'm suckered in, especially if it's re-hashed APX25 (and even if it's not).
It's always nice to have new products coming out, especially 'special purpose' like high or low speed. Hell, I'm happy that at least someone is still thinking of film at all.
