I don't have time to make any complex analyse, but it there's no glitch there IMO.
All lower limit/volume players get nice RB boost by those steeler rewards, SNs get that 1k too + more from milestones (most of them) and SNEs get $1200 more...
FR players are not affected but it may vary on some limits, SH players get about 9% more VPP than so far (still less than FR players but it's not that big difference now) <- this applies to NL; I'm not sure about FL..
just some calculation based on my NL50sh database:
before 5VPP/$1 change: 22 VPP/100 hands
5 VPP/ $1 (since mid of '09): 24.35 VPP/100 hands
5.5 VPP / $1 (since 01/01/2010): 26.79 VPP/100 hands
I
it!
