There are two answers there:
If you sustitue the TD for the mid point and the midpoint is less than 200 (our minima) you would go around outside the marker. If you just consult the table and assess that one of the three is inop then you would continue.
So I was hoping for some regulatory guidance on whether the touchdown RVR was required but I think I will have to ask for guidance to be put into our OMA.
