Not to burst any bubbles ...............but the greatest density emphasis is required at the gate, not the runway.  An airplane making a tight, low speed turn, creates a more tightly focused  downforce than one that is landing. On the same token, what do you think is the biggest cause of damage to aircraft interior floors, fat guys in loafers or 100lb women in 3" heels? (hint)Most people are surprised by the answer! The same general physics applies to the gate vs runway scenario.
