On any pool block % is luck based. During the period you mined we found a lower coin block by luck, next one had thrice as big coin reward.
This is common to all pools, it gets averaged out once you mine for all 24 hours.

Any issues on netcodepool, email:  inaun@netcodepool.org

Btw netcodepool is in mining business since more than a year, much older than any other pools you will find here. We have payed out over 70,550+ LTC over this period to users. 1.1 Billion DOGE have been payed out to miners, that accounts for more than 1% of the total coins.

Also, note that netcodepool is an admin on Dogecoin's official sub-reddit, /r/dogecoin so even the creators trust us You could have just dropped a mail or approached any online admin on chat.

During the major hack before last week due to which there was one week downtime, our hot wallet was stolen, but we made sure all users got their coins and paid them from our pocket (never made an issue of that) - thus maintaining the record of never loosing a single user's coin.

Always calculate the amount of DOGE you will earn in 24 hours based on your hashes on a website like coinwarz, then based on that join a pool which gets you the closest amount to that.
Make sure you spend atleast 24 hours on a single pool to get correct statistics.

Always research about the pool's history before you mine there for longer duration time, because it involves your "real money".
