When setting up yardage ranges for scoring in Full Impact, make sure there are not any gaps in your ranges.
For example setting up your rush yardage ranges like the following:
0.000-49.000 = 1
50.000-99.000 = 2
will result in a gap between 49 and 50 yards. If a player is projected to rush for 49.5 yards, they will not be accounted for and will be awarded zero points -- not your desired outcome.
When setting up ranges like above, make sure they are configured like this instead (notice the .99):
0.000-49.99 = 1
50.000-99.99 = 2
