Good: Pollen is compatible and blooms in sync, best pollination
Ok: Pollen compatible but bloom is somewhat out of sync, cross pollination is likely to be good most years, with perhaps 25% less yield
Poor: Pollen compatible but bloom is very out of sync, could have 50% less or worse reduced yield but some years could be fine
Bad: Pollen is not compatible, or very out of sync, unlikely to work most years
