While I stand by my comments above, defending of the scheme, I have to say that having read UV's (and Bar Shakers) comments on the weather, I don't support UV's position at all.
To me, the purpose of the scheme is NOT to provide a free landing fee of your choice, should the weather at your destination be crap both at take off time, and arrival time, when you have lots of options, in very good weather.
You were in far from difficult circumstances, and certainly (from the info you gave us) in no need of any particular assistance. Certainly not an emergency. A diversion perhaps. But was it an "emergency or precautionary diversion"? I wouldn't call it so.
Trying to claim a free landing fee under such circumstances, will only lead to the scheme collapsing, and ruining it for those in genuine need of an emergency diversion.
