As it says, we rewarded every share for the last 207hrs
Since you weren't mining for 207hrs, your fraction of the reward was lower.
e.g. if you mined for 100hrs then your reward would be about half of the fully ramped up reward.
24hrs then your reward would be about one eighth of the fully ramped up reward.
Also, it's not 1 shift, it's 207hrs of shifts for that reward.
The actual length is 5Nd+a bit, and the amount of time depends on the pool hash rate and the current network difficulty.
On the shift page, all the shifts rewarded goes down to the red line you can see by clicking the link above the shift list.
As I explained above, the pool uses 5Nd for the N in PPLNS
So your reward will take 5Nd to reach it's expected value for the hash rate.
It's not losing reward, it's spreading it out over 5Nd in the future.
At the moment 5Nd is a bit over 8 days (~207hrs)
Again have a look at this:
