V1min is defined as
(2) V1 , in terms of calibrated airspeed, is selected by the applicant; however, V1 may not be less than VEF plus the speed gained with critical engine inoperative during the time interval between the instant at which the critical engine is failed, and the instant at which the pilot recognizes and reacts to the engine failure, as indicated by the pilot's initiation of the first act
So, I stand corrected, but V1min will not be equal to Vmcg, as of the current FAR 25 amendments.
