By design, the APs tend to have about 150% of the WBL load for their levels. This is, again, by design, as it assumes that A: some gear will not be useful to the specific characters playing the adventure and B: some will be hidden or quest rewards that end up overlooked/unclaimed.
There is some variation, especially in the early APS, but this is the standard design philosophy for the current APs.
