I do not have the best answer. However, I did have the same conundrum. I used a food scale (regular scale didn't work) to measure out the seed and used my feet to measure out 1,000 sf in the yard. Afterward, I put the spreader at a very low rate, crossing horizontally and then vertically. Once the seed was spread and then the peat moss was lightly distributed on top (not necessary but nice indicator of water need) I put down a pre-emergent dose of Tenacity, to ward off poa annua issue, that is my number one nemeses. Of course, I ended the whole day with the dchall "buffalo stomp" so that the seed would marry the soil. I am only entering my second year as a lawn student...so take my advice with a grain of salt.

Turns out tarheelsol did have the best answer.

And the coolest new dance move...buffalo stomp...classic
