If I ever get 13K on Level 1-1, I plan to kill off all my men on 1-2 and enter my initials. Why tarnish the achievement with a likely 4,200 (or less) on the following rivet board? It's almost a guarantee. Seriously.
The same goes for my first 140K start. I refuse to allow for the possibility of forum ridicule: "Hey guys, check out this clown. He has 141,800 at the end of Level 04, then botches a routine back jump on 5-1, kicks a pie on 5-2, runs face-first into a spring on 5-4, and finally falls through a rivet gap on 5-6 while chasing a fireball with the top hammer. Never seen a meltdown like that before."
