The rules for the next draw (@bittybox you were first to notice):

* Real-name attested addresses get 1 point per GB of balance up to 10 GB, plus 0.1 point for each GB between 10 GB and 1000 GB, plus 0.01 point for each GB above 1000 GB.
* Unattested addresses get 0.01 point per GB of balance.
* 0.1 point is awarded for each GB of balance increase since the previous draw.
* 0.2 point is deducted for each GB of balance decrease since the previous draw.

The change introduces 0.01 coefficient for unattested addresses and very large attested addresses.  As a result, the weight of whales is further reduced.
