Completely agree with Denny.
First tighten your crush, and if you know your grain bill and strike volume you can determine the conversion efficiency which is closely related to how well the crush and dough in went.
Secondly, make sure you're stirring your heart out during dough in and the batch sparge.
For water volumes, you can use any software that's set up correctly. I completely unbiasedly recommend taking a look at my mash calculator,
http://pricelessbrewing.github.io/BiabCalc as it's very easy to use and will calculate the conversion, lauter, mash, and preboil efficiencies based off of just a few measurements. From there you can usually tell what the issue is (crush vs sparge).
As far as run off ratio goes, as long as they're somewhat close it's fine. If you use my calculator, and watch the lauter efficiency, there's little difference in a ratio of 0.4 and a ratio of 1.0 (equal runnings). For most brews, the difference is +- 1 %...
