perhaps we should revisit the question

that was posed.

The bags weigh the same. I was guessing that the numbers were related to
the percentage of components in the bag.


I don't think that's guessing. The numbers are the percentages of
nutrients. So, it sounds like
one bag has it being applied at a lower rate. That's the only way to
get higher coverage for the same size bag
with the same X-X-X percentages.

Yes! Lower rate of application because they are different products. There
are pieces of information missing -- the way in which the nitrogen is
available, and what is used to determine the spread rate. Even though both
bags are 24% nitrogen, the OP didn't specify how much of that is slow
release and how much is water soluble, which has a big impact on the
nitrogen's availability to the turf.

Additionally, everyone so far has assumed that the nitrogen is the
determining factor in spread rate. It isn't for the weed-and-feed, in which
the pesticide is the determinant factor, and which has primarily water
soluble nitrogen to combat the immediate effects of the pesticide and very
little (if any) slow release nitrogen. (This also affects the timing of the
next application . . .) Regards --
