got a 20/20 system up and running on a 2009 1250, have a couple hundred acres in the ground so far. some varieties I can get singulation down to .2-.3% skips and .1 doubles, others ive turned singulators down to 1.5 and had vac to 20, and still cant get rid of multiples. all have been medium flats, except for a couple bags of small flats.

finally i left singulators at 2-2.5 and ran vac at 14-18, changed varieties and it ran .2 skips/.0-.1 multiples. anything else anyone can think of? running strait graphite, too much if anything.

guess I want to know what else I can do to improve things, if I can?
