So basically this means taking into account whether there was MIMO in use (which may lower the transmit time)? My understanding is that (at least in Linux) this is encoded in the rate tables (i.e. a MIMO rate is a separate entry). Am I wrong in thinking so? Or is this something else entirely? -Toke
