Mine is not that high, maybe 200,000 earned, and about that spent, (over 14 years, of course, not in one year).
Don't tend to amass points, someone I know lost quite a lot in the Ansett system when their FF system went kaput with the airline.
Maybe 15% from flying (joined VFF in 2005), a lot from the FB collection system.
Pity that the SC collecting system is not up to scratch, sometimes my family spend $500 to $600 for a larger family group, in a month, but the SC earn from FB never goes to 5 or 6 VFF SC.
