In actuality K25 is more forgiving than a faster speed film.  Slower speed
films obsorb light at a slower rate obviously, that is why they are rated
such.  So if you over expose a shot on K25 for one extra F stop, it will
have one fourth the impact of overexposing an ASA 100 film by one extra F
stop.

This law of physics is why using slower speed film for night shots can be
much more desirable than faster speed films.  The slower thwe speed of the
film, the less ambiant light will effect the shot.  Thus allowing the
photographer more control over the end results.
