The improved and more-outside friendly GE was implemented after the first two matches of the season. The new line you referred is one of the improvements and part of the attempts of finding the cause of that annoying 24+ seconds bug. It may have had a positive effect, but obviously, did not fix it completely.
As for the percentages, obviously it's not going to be a super big difference right away, but we might consider upping the positive outside shooting effect next season too.
