So if you AOL is request 1 & 3, and mom-n-pop-ISP is request 2 & 4, your LTM load is not going to be anywhere near equal. You'll find that the load between your data centers will fluctuate frequently as there is no way for GTM to know the number of clients utilizing the response the LDNS servers out in the wild will receive.
