According to that chart, earning 12,000 Rank Points for the year, with at least 750 each month (to maintain tier 2 VIP level) will yield about 22% rakeback.
Notes: The chart is using the old dealt method for rake. The calculation is using the equivalent of TB bonuses for converting CP/PPS to cash (I'm not sure if this is exactly the same as buying into tournaments).
- Determine rake paid: 12,000 Rank Points (column 1) = $2,160 rake (col 2)
- Determine Accumulated RP Bonus: 12,000 Rank Points (col 1) = $150 Acc Bonus (col 5)
- Determine CP/PP earned (at tier 2): 12,000 * 1.5 = 18,000 CP/PPs
- Determine TB Convert: 18,000 CP/PPs (col 6) = about $322 TB Convert (col 8)
- Add Acc Bonus and TB Convert to get total rake return: $150 + $322 = $472 rake return
- Calculate effective rakeback percentage: $472 / $2,160 = 22% rakeback
