Calculating the worth of an extra % of CDR is a bit harder because nothing gives you flat CDR. If you subtract the gold value of stats from an item that has CDR to find what's left over, you get wildly different answers based off of what item you use. In general, is used to calculate the gold value of CDR, which comes out to 26.6 gold per 1% CDR.

Side note: 10 adaptive force gives you 6 ad OR 10 ap depending on if your champion is AD or AP.

#What does this mean?

Not a lot really. No matter which runes you take, the overall gold value of the stats is going to be pretty even. The only outliers are health and CDR, but the advantage only starts to show after about level 10 or so. It is far and away better to take armor/MR over health and Adapative force/attack speed over CDR.

It is aggravating though that you're essentially throwing 100g of stats away when you choose to take defensive stats instead of offensive ones in the flex line.
