Looking at this another way, you have a VMCG of 100 kts, in order to use this speed in a balanced field calculation you require a minimum runway length of x,xxx feet. So if your V1 is less than VMCG you are left with the following options:
1: Increase V1=VMCG provided runway length = x.xxx feet.
2: Use a different runway.
3: Use a different thrust rating.
4: Wait for the temperature to change.
EESDL, accelerate stop distances dont account for the use of reverse thrust, therefore how will the planned stopping distance to affected by the number of engines which you lose?
