Jeez, calm down.
The TBS concept effectively compresses the wake turbulence separation.
However, the spacing/separation tool is accurate down to 0.1nm so will allow Gatwick, or Heathrow, or any other airport if they deployed it, to more accurately refine the departure gaps in single runway ops. We all change the gaps in SRO according to the headwind and runway occupancy, but as you say vespasia to 0.5nm, not to 0.1nm increments.
