V2min can be limited by:

1.1Vmca

1.13Vsr or 1.08Vsr.(dependant on configuration)

At low weights, high pressure and low elevation you will probably be limited by the 1.1Vmca requirement. At high weights regardless of the flap setting you will be limited by Vsr. At the mid weights with low flap setting you may be limited by the Vsr requirement but as you put more flap out the Vsr may go below Vmca and then your V2 is based upon 1.1Vmca.
