I would apply in 2 groups. guys with points vs guys without points. This also breaks your tag number down some. If you are nearing the end of the draw and you draw a tag what if there are not 7 tags left? then you are all out. If you have a group of 4 and draw its ups your odds a little id assume.
Applying as a group in CO never helps your odds of drawing for the reasons stated above; it can either hurt your odds or have no effect on your odds depending on point totals, tag quotas, and applicant numbers.
You can check historical draw reports to see if applying as a group/groups is likely to have any effect on your odds of drawing a particular tag. If everyone in the group is above the minimum point pool, group size won't have any effect on draw odds. If anyone in the group is in (or below) the minimum point pool, the group's draw odds will suffer compared to applying individually (or in multiple groups). You can't know for certain what the minimum point pool actually is until after the draw, but you can get an idea by looking at past years: https://cpw.state.co.us/thingstodo/Pages/Statistics-Elk.aspx
