p2pool - Decentralized, Absolutely DoS-Proof, Pool Hopping-Proof Pool [archival]

I'm a bit confused with the fees taken. Is it right how I understood it?:

Code:

50 BTC/block
+ X.XXXXXXXX BTC from fees of transactions in the solved block
= Total BTC to be distributed

Now:
0,5% of 'Total BTC' goes to the one who finds the block
0,5% of 'Total BTC' goes to forrestv
What remains is PPLNS (Payed Per Last N Shares)

Please confirm or correct me. Thanks.
