Hello again,
Indeed, the difference may be less than "10% of one HP" but
that would seem to be an odd way of looking at it. These are
not tugboat engines we are looking at.
Assuming for the moment that the wattage is accurately
described, is not 325W 50% more power output than 250W?
The important comparison would not be in the absolute
difference, but in the relative difference.
All the best,
