The date by which I had to meet the criteria for SL was August 31st. I passed this mark last week and still have some 17,000 miles to accrue before the 31st. I notice that on the 4th of August, the option of continuing to Gold was taken away and my mileage re-set to zero and silver. I am not complaining, in fact, CX are doing me a favour. The 17,000 I'm doing in the next two weeks can now be used to re-obtain SL.

My question is, was it a computer/automatic re-set or a 'human' decision? Just curious as to how it works,
