Thanks a lot for your explanation Meikleour
All the while I have been switching on masters at N2 of 22% even though the engine was accelerating,as the SUP procedures does not clearly enlist the factors that would help me decide whether to let the N2 flatten out above 22% or start the Masters at 22%. So your suggestion is if the engine has a history of high EGTs during start, then delay opening the fuel flow. The weak bleed source is easier to identify as N2 wouldnt build up sufficiently, so you might want to reduce the load on the APU by isolating the consumers such as fuel pumps etc.
