Was clitching at straws, the type of cable with the black outer insulation is the up to date type, difficult to make out on the photo but that looks to probably be the latest type of block at the top of the pole judging how far it projects from the pole so "blue beans" wouldn't be an issue. Though I've got to admit it's wrong to try and diagnose from remote for the network.
You current figures look great though, so far, fingers crossed.
