I was gonna say only coming the afternoon but brekkie down at the Old School cafe sounds alright to me. Might make that, I pass that place often and always wanted to know what it was like...
As to people being concerned about the rollers, Charlie's rollers put me at 248bhp a couple of years ago which I was pleased with :) Though I'm not expecting that this time 'round, because my car is broken (though I'm not sure how broken, natch

)
you can not accurately measure flywheel power with the engine still in the car!
it needs to come out and done on a test bench / engine dyno to get a proper engine power figure.
something like this (its from Norris Designs)
as Hedge says...they do some strange witchcraft / creative accounting thing to give u a number that u can then argue over at the local.
You coming down to this Lee? Been ages since I've seen you!
