Question about W&B on a 701

I am trying to do my weight and balance figures on my 701. I have built it without slats. On the worksheet it calls for the datum to be taken from the leading edge of the slats I do not have. Should I take measurements from the leading edge of my wings instead or should I add 4.75 inches to that number and use that as my datum.

If I try to use the new datum from just the wing, all of my calculations put my CG way forward. Like empty CG is coming out 3.75" when its supposed to be between 11" and 20". Has anyone else run into this? Should I be using the same datum without slats? Help please. Very near inspection for airworthiness.

Thanks
