Hi guys, my pools include an extra rewards for who found the block, this reward is "Finder Reward"

The scheme is:

Block Reward = BR
Pool_Fee = 1% x BR
Pool Reward = (BR - Pool_Fee) x (1 - Finder_Reward)
Finder Reward = ((BR - Pool_Fee) x Finder_Reward
Miner Reward = Pool Reward x Round Percentage

For example if Finder Reward = 20% , Pool Fee = 1% , Block Reward = 4, and miner has 3.5% of the round

Pool fee = 4 x 1% = 0.04
Miner_not_finder = (4 - 0.04) x (100% - 20%) x 3.5% =  0.11088
Miner_who_found_the_block =  (4 - 0.04) x (100% - 20%) x 3.5%  + (4 - 0.04) x 20%=  0.90288

System Reward = PPLNS
Finder Reward = 20%
Pool Fee = 1%

Block Reward = 4 ETC + TX (transaction fee) + uncle inclusion reward = Complete Block Reward
Uncle Reward = 0.125 ETC

Happy Mining !!!
