On a longer bar, you might have enough range of adjustment to start with a slightly smaller chain loop, so that you can compensate for stretch. On smaller saws this is not always the case.
I have an Echo that takes 57 drive links and will absolutely not accept a new 56 DL chain. But I am told that it may accept a 'stretched' 56 link chain. Of course, an outboard clutch makes fitting a tight chain more difficult compared to an inboard clutch.
