Damage per second Index

I decided to make a damage per second index on all of the weapons within the Lord of the Rings Mod; as, I have realized that this has not been done before and this is a resource that I would have liked to use in the past. So, how am I going to do this? With an expression that I will show in a few moments. Now, since this mod has weapons cooldowns (Ugh! its like 1.9 all over again) of at 100%, a sword, the cool down is .75 seconds with a halberd/longspear (50%) it is around 1.5 seconds. So using this I will be able to determine what is the damage of each weapon inside of the mod.
