MANFOD
It wasn't me that posted ACL data, but like you I recall reading about it on this site somewhere. And the % increase for STN was quite a bit higher than for MAN, so the gap between the two airports will continue to close.
Maybe this discussion is better on the STN or MAN threads...
Meanwhile here is the link to ACL
