Undefined Grouping Question

Hello, my name is JDeezy and I am an alco-- I mean – I have trouble with undefined grouping games.

Currently scoring between -0 and -2 on LG, but have posted a couple big numbers because I hit an undefined grouping game and things go haywire.

I have used the LGB method of mapping out the conditional rules and looking for relationships between the rules. I’ve seen a couple other methods around, such as the Atlas approach which is posted as an attachment here: http://www.manhattanlsat.com/forums/diagram-t33.html?sid=5162baa899eec52d64bdd3ada8cd1f9b

Wondering if there is a general consensus for which method is best for diagramming undefined grouping games?
