I was curious and decided to point some hash there.
Doubled rewards for LiteCoin mining ends in [6 days, 33 minutes, and 54 seconds]
To prevent getting 51% of the Litecoin network, the reward multiplier will be adjusted according to the pool speed. Current multiplier: x1.25.
Pool Speed Reward multiplier
0 – 40 GH/s x2
40 – 60 GH/s x1.25
60+ GH/s x1
So that's how they weasel out of the promised double rewards. More arbitrary bullshit ...
Not really. Stil 1.25x is more than anywhere else...
