Bugger the mini backtrack, there's plenty of margin in the takeoff calcs, gently line it up without scrubbing the tyres but dont use more than the lineup allowance.
Most jet aircraft using asummed temperature takeoff method include about 250 metres of pad.
Calculations with headwinds automatically factor in only 50% of that headwind actually being available, alternatively tailwinds are factored to 150%.
Maybe for large aircraft like the B744 or A380/A340 when conditions are limiting, otherwise it sounds like the 737 boys are lining up like the long wheel base big boys do.
