To answer your first question about percentage amount The third line for 1990 2000 35 50 was turned into 40 60 while the forth line for 2000 present 50 75 was turned into 60 80 So we still have equal amounts overall To answer your second question We currently don t have Page 2 anymore it was created at one point but it was re merged with the original And the main reason we decided to trip the bottom 20 million is because the list had passed 350 000 bytes For many months ahead we won t be modifying the length of the list And we may never will if we manage to keep the bytes around 250 000
