Just like there appears to be an enclave of SK (Stockport) in the
middle of OL (Oldham), and OL4 apparently doesn't exist at all, while
there are two OL15s, and OL2 is apparently centred on the Woodhead pass
towards Penistone.

It also doesn't understand the Cambridgeshire recoding. CBn and CB2n
aren't horribly intermingled. Rather, CBn codes outside the city
boundary are being changed to CB2n codes, sometimes by just adding the 2
and sometimes by more drastic changes.
