Its simple. Because on those short blocks, the block was solved before you submit even one share. Check the amount of shares they were submitted, its less than 300 shares. 1641 people were mining at that time, the block was solved before everyone submitted their shares!
ok, this may be the reason
however this pool should be PPLNS and I understand PPLNS means that when block is found you will look at last N (don't know the exact number) shares and distribute payouts among miners contributed to them proportionally to their contribution.
So also during short round like 10000 shares if N is e.g. 500000 you should recieve your payout even if you didn't have shares in this last 10000

Therefore this means that this pool is rather RBPPS based???
I heard the pool has been RBPPS for the last couple weeks or so.
From
https://www.wemineltc.com/gettingstarted , down bottom :
Our Pool uses RBPPS or Round Based Pay Per Share. What this means is simple, you get paid for the amount of work you did to find the block!
EDIT i just noticed it wasnt changed on forum topic, i changed it just now
I guess this explains a lot. It still says PPLNS in your signature as well the litecoin pools comparison wiki page.
Doesn't this effectively penalize people who are mining with shares at high difficulties because of vardiff? For example, my rigs of 3x 7950s get shares of 512 difficulty that take slightly less than a minute to finish. If the round ends before that minute is up, it effectively means I submitted no shares. On the other hand, if I could manually select a share difficulty of 128 or less, it means that I would have shares submitted every few seconds and get credit for that block.
I'm just wondering how this works because after mining for close to 24 hours, I ended up with 2/3 of what I normally get on other pools.
