Right when you enter the GFMC Compound at the beginning of the game, it's possible to ghetto jump up to the Missile door area without triggering the cutscene.
If you blow up the box, grab the Missile Launcher, and activate the cutscene afterwards, the box respawns with another Missile Launcher. This allows for 2% from one item, as well as obtaining 10 Missiles instead of 5. If all the items are collected, it's possible to grab a total of 101% items, but the Missile counter cannot reach over 255.
The SDA does allow this glitch, but does not allow it for 100% completion unless you obtain 101% (so you can't skip a random item and claim 100%).
