I just want to point out that if you really are spamming IB, you can average an IB every 6.1 GCD's for about 3.5 minutes. After that it falls to about every 6.33 GCD's. Not saying you should spam IB and obviously you will get a ton of overhealing.

If you start counting GCD's with the first IB and not at zero Wrath then you will be at 5.4 GCD's/IB after 3.5 minutes and you will slowly start converging to 6.33 GCD's/IB.

Also you can average 4 IB/minute for 3.5 minutes. After that you converge on 3.8 IB/min.
