Decision tree on how to get to a final stand of 100,000 plants per acre using a planter?

                                            + Good seedbed ("tillage")
                                            + 1-1.5 inch planting depth
                                            + Relatively new planter (< 5 yr old)
                                            + Moderate planting speed (< 6 mph)
                                            + Excellent seed quality

IF you have 5 "+" your seeding rate will be 125,000 seeds/acre
IF you have 4 "+" your seeding rate will be 140,000 seeds/acre
etc.
