Robini this is all getting a bit autistic. You asked an interesting question about the relationship between weight and takeoff roll. You (an apparent 15 year old spotter) have had some reasonable answers from people who know what they are talking about. The answer is, it depends on a number of factors.
If this particular example is really so important to you then provide the runway used, weather and aircraft registration and no doubt some kind soul will look it up for you.
I am pleased you have flown on the NG and seem to have enjoyed it. There are conditions when we takeoff using unreduced thrust but they are relatively few and far between (winshear et.). There are of course cowboy outfits that still operate in the dark ages. As an example we were horrified when we got one of our aircraft back from a lease to discover that it had been regularly going unreduced at great cost to engine life.
Believe me the guys who are using more of the runway are doing things right.
