All of the weighted BiS sets at around the projected 720 accuracy are all roughly the same. 600 DET, 600 SS, 1030CRT, tbh.

As for the sets for the lower accuracy requirements, I think it would be best to solve it for the highest accuracy requirement, then "lock" the melds into the "BiS items", when solving for the accuracy tier below.

That way you won't end up with something dumb, like two different meld combinations for 1 piece of equipment, for two different accuracy requirements.
