N1 profile for breakaway

I am a student and would like the following info to validate my emission model.

I would like to know N1 profile from 0 kts - breakaway i.e., still to taxi at MTOW. By profile I mean the thrust level and the duration for which it is maintained.

For example, 733 - 33%N1(10-15 seconds)(for breakaway) - 22%N1(thereafter for taxing).

I need this for B737, B757, B767, B777 and B747. Approximate range for each of the parameter( N1, time) is good enough.

Thanks
