Not at all the situation. . .. .The speed ratio for the BFL case will vary from aircraft to aircraft and runway to runway. Depends on factors such at pressure height, OAT, gross weight, wind, runway slope, configuration deviations .. etc etc etc .. most times, the ratio ends up being less than 1.00 for the Types with which I have been involved. . .. .Why are you so concerned about the V1=VR case ? There is no particular significance associated with this case .... except that the ASDR is greater .... and that might well be very significant.
