I'll attempt to answer that. I believe it has to be down to both.
I would also like to add that 2 and a half hours to run a meeting is unnacceptable, but the sun delay (God knows who called the interval, as the rulebook states you can't have an interval before heat 10) didn't help. On top of that, I made it 8 re-runs last night, a couple of which could possibly have been avoided (?) and we had a repair of a air panel in there as well.
