I agree, don't get hung up on the ideal schedule. You might have a doe the while she produces great kits, maternity is hard on her so, you will want to give her a few weeks rest between weaning and mating again. (My M&M is like that.) Your strain may not be to weight until 10 or 12 weeks. Youre better off having more does and giving them a rest form weaning to mating again. You also have weather to consider. Unless you have the rabbits indoors and climate controlled, it can be too hot or too cold for breeding.
I have 5 does, I breed in pairs (for fostering reasons) and breed a week apart. I had six does but, had to retire on for this season and, wanted new blood so, I have 5 to start the rotation and one more that will be ready to add in on the next rotation so, will have one doe that has to kindle out of sync with any others once this year but, she is a proven doe and will have 6-8 kits and be fine. She will sync with the new doe next round (in case the new one need some foster off, I know my old doe will take any kits I give her - she has fostered for me several times. One of those does that sort of give you the "Okay, whatever you say." routine over anything you do to or ask of her.
