That is the point. If they don't accumulate (most actually don't), then it is not evolution. The problem with many trying to assert the validity of results from microevolution experiments is they include variables that eventually cancel out due to simple Darwinian mechanisms. It's like saying a mother who has had twenty children added twenty new citizens who will be able to vote one day but later you find out only one survived past childhood.
If they accumulate or not or at differing ratios would of itself have repercussions.
