Support is ****ing clueless, wow.
To clarify: I've not noticed any inconsistencies personally in VIP points balances and actual VIP points earned. Are you sure you didn't earn the other 8 points last month instead? (anything before 10 days ago?).
RB players indeed DO earn VIP points, at half the rate VIP players do, afaik. 1$ in Tournament rake would then earn you 3,5 Vip points, the rate at cash tables is around the same, but depends on the table size. Bigger tables with more players will earn you more VIP points per dollar, HU would earn you the least.
FPPs simply don't exist anymore on Lock. Maybe there's still some internal system they use for it (which i doubt much), but it's in no way presented to their customers at least. I'm 99% sure she's just really clueless
"Bonus will be paid out in increments of $5, for each 84 VIP points earned." This is entirely correct for you aswell, but this means you earn the bonus at half the rate aswell: you earn the required 84 VIP points at half the rate, after all (compared to VIP players).
Furthermore, i suggest swapping over to VIP once you hit WhiteVIP: the bonus equals to around 40% Rakeback in itself, earning this at half the rate obviously means 20% lost. WhiteVIP (15% RB) vs RB (36% RB) = 21% difference, -20% = 1%, but then you also earn VIP points at half the rate (which can be converted to $), and you earn Rake chase levels at half the rate.
Just a suggestion ;-)
