I would cut it. It sounds like the only way you'd regret cutting it is if it lost accuracy, and most people say that's not the most likely outcome.
You say you havent done a full 10 or 20 shot group yet, I'd say go shoot a 20 round group. I think 1- that group size is going to be bigger than you think, and it will make you less scared to cut it, and, 2- you can shoot a 20 round group post-cut for a true comparison.
