stop thinking so much and just throw the deeks out
When I started duck hunting 45 years ago, I also use to try all the J Pattern, X Pattern, etc. and always seemed to have the wrong letter, at the wrong time. After a few years experience, I just went with common sense. Wind blowing right to left, set up decoys just to the left of blind. Left to right, set decoys to the right of blind.
Lots of hunters like ducks decoying straight into blind, personally I don't care for that, due to ducks looking right at the blind when coming in. I am a puddle duck hunter, mainly mallards. The right to left, and left to right method, let's me set decoys close, and only haft to worry about hiding from which ever way you are expecting ducks. By the time they are in the hole it is to late for them. Anytime I can get the sun behind me, I make that happen also, but not a requirement.
I also like decoys set loosely, no decoy closer than 3' of each other. Ducks tend to huddle up tight when they are nervous, and ready to fly. Match your spread to the what the ducks are showing you in the area. If ducks are in groups of 2-10, my decoy spread reflects the ducks in area. Maybe 18-24 dekes unless there are large numbers of ducks moving with the front. If ducks in the area are sitting in groups of 12 or less, they are skiddish of 3-4 dozen spreads, when they haven't seen groups like that since the were in Canada.
Once I started matching my spread to what I was seeing in the area I'm hunting. I have been MUCH more seccussful.
