I guess your full rated is 26K and now you are using derate 1 (TO-1) which is 24K.
Then full N1 at 15°C is 94.6% and reduced N1 with assume temperature of 31°C is 93.4%. Some people are confused because of the way you stated things.
Without deep study at first sight, I think the 3051m distance is wrong (maybe mistaken)...2051m is more logical.
Can you please check those distances with full rating (26K) and TO-2 (22K) with the same figures (OAT, Flaps, ...etc)
