The purpose of the 85% component at the planning stage was to give a buffer so that the AARC did not have to manually replan things at the last minute. In terms of feasibility of leg length this is unlikely to be an issue for Voyager. As far cherry picking both systems, unless I have missed something, both have 2 weaknesses which I think should have been addressed long ago. The systems seem only to deal with the accompanied portion and the bracket selection process needs adjustment to place the final bracket in the optimum position.
