Are all strategies to mine PPCoin Proof of Stake blocks equivalent?
alice finds the most blocks. 520 confirmations + 30 days of no-stake makes a maximum of 12 blocks per year from the same coins. compound interest makes no impact at all with 12 compounds and 1% ROI .she makes max 1.00437%

bob makes a perfect 1.00% but loses a lot of stake and risks not finding a bloc in that week.

charlie makes 1.00-1.00437% depending how often he finds blocks.

actually, they can find much more blocks, as parts of wallet have different age, but its just as running many wallets, there is no difference in maths.
