Please correct me if i understand this wrongly. I sold my miner about 2 weeks ago, and upon selling this was my outstanding eligius balance:

As of last block:   0.00040948 BTC   97.22%
Estimated Change:   +0.00000000 BTC   0.00%
Estimated Total:   0.00040948 BTC   97.22%


If i'm not mistaken, shouldn't the share reward be paid to 100% over time even after i stop mining?
I remembered myself stopping once in the past, and the reward eventually crept up to 100% when more blocks are found.
Mine has been staying at 97.22% for a long time. May i know what's the reason behind it?
The remaining ~2.8% of share reward worth about 0.3BTC from the Max Reward chart but i'm not sure if i'm interpreting it correctly. (Difference between everpaid and max reward)

Thanks!
