Thanks for the reply.
Here's what zpool says for phi:
Mining on a single wallet at 7.8 GH/s, 95 miners
Name
Amount
Diff
Block
TTF***
Hash**
Profit*
Lux (phi) 10.00170218 LUX 26.616 k 170 217 (1%) 4 hours 7.8 GH/s 0.01523
So it shows 4hrs.
Does that mean, that when the block is found by the pool (in average 4 hrs time), then all accepted shares to pool will get earnings?
Depends on the setup of the pool, proportional or PPLNS. But the general idea is that you get paid for how much you mine only if your pool finds a block. If you want to get paid more often, join a pool with a higher hashrate. However, each payment will be lower than those of your current pool. It balances out given enough time.
