Below left is screenshot of my trickster rogue ability scores (lvl 60 - half-orc)
Below right is another TR that was in my group (lvl 60 - halfling)
Why are his ability scores so higher than mine? When I rolled my character i kept rolling until I had the highest possible.
Yet this halfling has more in every stat... how?
Halfling TR has more than me: +2 str, +2 con, +2, int, +1 cha
???
I took the screen shots at exact same time inside a dungeon while grouped.

As such a character with the biggest numbers initially won't necessarily result in the highest total amount of points as the points you earn while leveling are granted 1:1.
I haven't done the math to see if the rolls do vary when set to 8 but I can tell you rolls which include 18's as base rolls always have lower total points as noted by zephyrwestwind.
