This is not a standard monero mining pool. Instead this pool uses the mining script from coinhive and aggregates all hashes from all participating sites on one site key. This way we can reach the payout limit of 0.5 XMR together which would need much time if everybody tries it alone. You don’t have to wait until we reach this limit. I have already some XMR which will be used to pay you as soon you reach 0.1 XMR.
There is no information about when the last block was found because coinhive does not provide that information.
They just provide a formula for the value of 1 000 000 hashes in XMR which depends on the difficulty of the network difficulty and the average block reward. This information is shown on the pool page. As the difficulty and block reward change the XMR value for the hashes also changes.
Every 5 minutes the pool calculates the value of the hashes you did in the last 5 minutes and add it to your ‘Total XMR’ value.
So if the difficulty rises your ‘Total XMR’ won’t get less, it just will not increase slower. If the difficulty gets lower you ‘Total XMR’ will increase faster.
I have changed the description to 80% miner, 20% pool because I think it is easier to understand. You get 80%, the pool gets 20% from the payout that coinhive does.
I hope that clarifies some of your questions. I will put this description on the pool page.
