Landing zone question

As your town gets larger, the effect of expanding a row or column has less and less impact on your landing zone. I'm horrible at math, but adding a sixth strip to a town that is only 5x5 would shift things over by a much greater ratio than adding, say, a 14th strip to a town that was 13x13.

If your landing zone is precisely designed to be in the crosshairs, then prepare to move it with every new strip. Fortunately, (said wryly), EA doesn't give us that to worry about much.
