Thanks for the link to CAP493, Crash and Burn,
This thread was started with a Medium following a Heavy, but I see that the A380 has added further complication to the rules.
And, for the benefit of anyone who thinks that discretion might be used in a strong crosswind, this is what CAP493 (Section 1, Ch. 3, Page 12) says in relation to the UK:
"NOTE: ATC shall apply the minima as prescribed..., irrespective of any pilot request for reduced wake turbulence separation. ATC does not have the discretion to reduce wake separation minima."
