Number Fission Beta

Odd numbers are stable, even numbers are not. Even numbers split into their 2 neighbouring circles. Your job is to reach the highest score possible, while making sure the system doesnt enter an infinite loop. In Classic mode, there is an even tighter restriction - splitting can only go on for less than 49 iterations. If you want, you can test the limits in Longest Cycle - see how long splitting can go on for, without entering that dreaded infinite loop. Thats all you need to know for this puzzle...
