How accurately can you make a peace sign? Can you adjust it for the different outbound angles as fullness varies from 1/4- to 3/4 full? Can you predict which side of which ball in a cluster you're going to hit after 2 feet of travel (from the OB to the cluster) with a 2/3-full hit?
Yes, the peace sign is much easier, and much less accurate.

yes the peace sign gets you to the neighborhood of where the cue ball is going
like everything else
the answer to where the cue ball goes EXACTLY
is table time figuring it out
setting up a shot angle and watching where the cue ball goes given tip placement
to learn exactly where the cue ball goes...
there are some billiard systems that will predict this but they are based on 2 ?mother positions so they dont apply to all situations
