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.
