I did basically the same calculations back on the 7th. I ended up sacrificing a few days age back to the 29th of December to re-combine about half of my balance into blocks of 8000 or a little more. I started this progression with my blocks that were just about to start gaining weight. In appox. 3 days the larger blocks will start gaining weight. It will be interesting to see how this progresses. My blocks that had started gaining weight on the 29th I left intact. To date I still have over 30 blocks of coins in the 3000 to 3500 coin size that have been gaining weight that date from 12/13 to 12/29 and on average 3 to 4 a day are staking.
