Geez Messiah, are you STILL flogging that well and truly dead horse. You still don't get the concept of MBRW do you!
To answer your question. I go. Why? Two reasons. 1. I wouldn't be looking at the totaliser anyway as the engine instruments and the performance are more important to me than the fact that the fuel sloshing towards the back of the tank will have registered an increase of a couple of hundred kg. 2. I was under the MBRW weight when I released the brakes to begin the take off roll. The totaliser isn't as accurate when under acceleration which is what we are doing when passing through 40-80 knots on the take off roll.
When I released the brakes at the start of the take off roll (hence the term max brakes release weight) if I was indicating under that weight I'm legal. If I was 100kg over, I'm illegal.
Get it yet? It really isn't that hard!! Who gives a stuff what the totaliser says at 40, 80, 150 knots or at any other stage it is under significant acceleration! It's MBRW that matters!
A wise mentor once told me that sometimes it's better to just shut up than continue to dig the hole for yourself. Trust me, stop digging.
