That is correct. You would go down as 2.75 points, probably not the best place to be on the scale. A good place is right above an integer cut-off to maximize your points(e.g. 2.25...). If the unit you are applying for historically awards a small percentage of tags to those with 2 points, you will be in 100% with 2.75 and will beat all of the 2.5 groups.
I love the way Wyoming averages their points. You can have one person with 4 points and another with 0 and go into the draw as a group with 2. The odds on this site break things down by half a point (e.g. 2.5) instead of by all of the options because there are just too many options between 2 and 3.
Best of luck.
