Hope you can help with this as my excelskills are severely lacking 
We are introducing a bonus scheme in work for a bit of fun, hopefully to get a bit of healthy competition going between various teams. We had an old bonus system before my time and it is this they are looking to go with again. I want to use excel to calculate the bonus/points.
The target bonus needs to be easily changed, but say for instance it needs to be 96.8%
If a team gets:
Between target and +0.99% they get 4 points
Between +1% and +1.99% they get 6 points
Between +2% and +2.99% they get 9 points
Between +3% and +3.49% they get 14 points
+3.5% and above they get 16 points
Hopefully someone can help with this.
Thanks in advance.
