One degree outthrust on the left side is insufficient to provide any elimination of the critical engine (aways the left engine when both rotate the same direction and normal engine direction). The critical engine is the the side that causes the greatest detriment to aircraft performance when that side fails.

Also one degree will not buy any additional time to identify and react with the appropriate rudder untill you begine to get up to around four degrees.

I always use equal out thrust on both sides and start out around four on all my conventional twin multi's. On my Quads I use two degrees on the inboards and four on the outboards. The triples typically do not need the out thrust at all and the six pack only has out thrust on the outboard pair.
