As you can see from the table, made with Libre Office, we should get a halvening every four years. This is the expected distribution. Theoretical Coins is rouneded off the to the nearest integer for easier display.
I've taken into account the changes made by 
According to Scot Bot these are the statuses of these three currencies: VIBS, POB, and LEO.

About 3% of total Proof of Brain rewards have been distributed. Now according to Hive-Engine.com website, LEO has a circulating supply of 7.992 million but Scot Bot reports 3.418 million. The Hive-Engine website reports 248,606 VIBES circulating. The Scot Bot reports 137,923 VIBES. The Proof of Brain is the only one that has agreement between Hive-Engine, and Scot-Bot and my calculations. I guess the difference is something like ICOs account for the differences.
