There was an article posted this morning that explains why there may have been an "unusually high" dividend payout

This was the original article quote
"COSS first weekly dividend was distributed on 10/10/17, and it came out to a 10% annualized dividend. Likely the reason it was so high was that many did not correctly stake their tokens for the dividend distribution."
