And you're lucky with that build time, if it was more recent it'd probably be CCA or even CCS. When we redid our place a few years ago I went and bought a drum of plenum cable and told the electricians to use that, so I know what went in there. Overprovisioned slightly but who cares, I had a whole drum of cable and a 48-port switch so may as well use it all.
