I would say 6-0-6-0 makes sense at D2/D3. Just too hard to get 6 good guys in D1, every good player is a battle. And then throw in EEs and basically there is no real plan in D1.
Basically, you lose a recruit on the last day and take a walk on and then you have an early entry and your 6 / 0 becomes 4 / 2 just like that.
As I said, you can do that in D2/D3. There are much less battles and you should be able to stick to plan.
