Nope...nothing that complex. A "mission point" is not 1 percent. Everything in a checklist (like this one
) counts as a single "mission point" (i.e. a specific requirement has been met)...with the exception of rampages (a single "mission point" awarded after all 35
have been completed) and hidden packages (1 "mission point" after every 10 collected). None of the GTA3-era titles award different percentage amounts for completion of differing tasks...although the number of tasks varies between titles. Similar tasks between titles are sometimes handled differently, too. "Paramedic" in GTA3 awards 2 "mission points", for example...since you get one for each unlockable at levels 8 (adrenaline) and 12 (infinite sprint). Unique Jumps in San Andreas award nothing.
A storyline mission's completion awards the same amount as any other required task...1 "mission point". So in GTA3 and V.C., often you'll see the percentage change, but sometimes you won't (fractions of 1% are not shown).
For a quick example...try this simple test:
When you begin a new game, stepping into the pink marker inside the hotel counts as a storyline mission completion (you've finished "In The Beginning..."). Checking your stats, you'll notice that it has not changed from 0%. If you then complete some other task (such as collecting 10 hidden packages), the percentage will finally show a change to 1%.
Start a new game and pick up 10 hidden packages to get a mission point (you can probably remember 10 locations without looking at a map). The percentage will not show a change once 10 have been collected. Then go visit the hotel to complete "In The Beginning...". The stat will now read 1%.
Notice that it didn't matter which was done first. The storyline mission completion did not show a percentage change in the first test, and did in the second.
Was it a different percentage in each test? No. The tasks were just "worth" less than 1% each...so it took another task completion to show the change.
