Although I am not versed in the science of performance calculations, may I suggest a simplistic comparison with SEN who have a TORA/TODA 1739/1799M for both runways? What do EZY/RYR achieve with that?
On occassions in my distant past we had a number of jet operators requesting a 02 departure, with a tail wind, due to the improved declared distances and obstacle environment - even with the rail shed!
