How Often Do The Parole Board Sit?

PFV get a fair few emails from prisoners families and friends asking how often do the Parole Board sit.
Well I'd like to know that one as well and I have asked about but no one seems to know.
I suppose they sit quite a lot when all said and done, so I sent our blog's photographer, Leve, out to do a bit of investigating and here's what he came up with. It does look like the Parole Board sit a lot, so I guess we got our answer!
