The reason they contradict on front toe is because it depends on many other factors.

I can take two of the exact same cars, let's say Xray T3s. I can put a different set-up on each one and give them to two different drivers. My instructions to these two drivers will be to experiment with front toe, both in and out in different amounts, document its effect and write a report for me. Because of the way I have set each car up, the reports I get from the two drivers will be exactly opposite from the other.

That being said, most any properly set-up car is going to work best with a small amount of front toe-out. A car that works better with toe-in probably needs more ackerman in the steering geometry.
