Also the top must be loosely attached with buttons to allow movement.
I'd give the table top more overhang on the sides and both table and benches a long overhang at each end say 12". It's fairly traditional and is practical - it makes general movement around the table and benches a bit easier esp if you are stuck for space.

The only time a breadboard end will not move is if the moisture content of the timber never changes over the making and lifetime of the table(and therefore the wood always remains the same size). I think this is a dangerous assumtion to make.
You can leave the wood to season for as long as you like but if the moisture content of the wood changes (because of varying humidy levels with the seasons for example) the table top boards will move across thier width. This movement, because it is across the grain will be more than the breadboard end (which in comparison is moving along the grain) and a step will develop.
That's one reason why I don't like breadboard ends unless they are made in the Green & Green fashion to hide this movement.
