Compared to RA (50 nights), SPG's 25 stays requirement for platinum is extremely easy to reach and maintain. (In 2009, I renewed SPG plat by mid February).

But anyway,
Mrs Chinatrvl, who I refered, was surprisingly granted another year of RA with 48 qualifying nights (+ at least 6 or 7 nights non-qualifying IVFF1 stays), including around 5 or 6 different ICs.
