What do the numbers on a broadcast spreader mean ?

I have some grass seed that says it should be sown at 15 seeds per square inch, and that 5 is too low and 30 is too high. My spreader only goes up to 15, so I have a feeling that's not what the numbers mean since the grass seed package seemed to indicate that 15 would be a "somewhere in the middle" kind of number. Any ideas ? It's a Scott's Edge Guard spreader, and the instructions that came with it don't tell you what the numbers actually mean, unfortunately.

1. The numbers are relative to the amount that needs to be sown. I don't know exactly what the ratio is for your model. Alot of the times, they will have the corresponding number on the bag of fertilizer or whatever that you should use for a couple different models of spreaders. You can go to the store and check a bag of fertilizer to see what they recommend, but if it were me, I would just set it at about 6 or so and start walking with it a few feet. Then look down and determine if you need to turn it up or not. Like the package says, you should see about 15 seeds per square inch. I have a Scott's spreader, I don't know what model it is. I usually set mine around a 4 or so. It's really not an exact science and it's ok if you set out a little more seed. Flordian: She's not using a Scotts product.
2. They correspond with the suggested setting on the fertilizer bags. If using a Scott's product just set it at the recommended number.
