Also if you want an even emergence ground speed is a factor. If you plant at 6 mph the row units will bounce more compared to 4.5 to 5 mph.

Not mentioned, but important. Cold temperature germination test your seed. On a low scoring seed, you are more likely to get erratic delays in germination if planting into 40-50f soil. Worst case this translates into an overall lower stand as well. Maybe unscientific to the lab standards, but taking 2 samples, soaking at 40 in farm soil, then returning to greenhouse led to 90% emergence for one sample and 50% for the other on day 5. The interesting thing is the lower scored sample didn't have another emerge for 2 days with a final 70% stand. OR wait until the soil is 65 and you eliminate this problem. Good luck.

funny how all the fields shown in this video have been tilled at an angle to the planting direction

Brian had a hard time pulling the trigger

Chickweed??

If you can go slow...go slow...the first man to 400bu twenty years ago did it with a finger planter...but he would put a can of coke on the planter...if the can fell off...he would slow down.
