I really had limited idea about the green group either. Pretty much darts throws made from myself.
I put up stats tables post 620 if that can assist you.
Due to the leg count switching from 11 (Rd1-3) to 19 (Rd4) I feel it keeps the Rd3 entry guys in the loop. I've chosen to go a mixture with 2-2-2 for entry rounds, whereas
@Connoisseur has gone with 3-2-1. I'm sure there may be entries on their way which completely bypass Rd 3 and go for gold with early selections. I expect the less prevalent method to be swayed to majority Rd 3 entry, but that doesn't mean that strategy can't work either.
