Since there is not a 99% chance the observer is in the non-decay 'world' and a 1% chance he is in the decay world--but is (if taken literally) in both world 100% of the time--it would seems that when repeated numerous times, most of the observers over their 'histories' would not experience a 1% decay rate (But rather something between 1% and 50% rate of decay.)

The only solution I can think of is the the 'non-decay' world decoheres into 99 'worlds'. But since I have not seem either this problem raised or this solution offered, I must be missing something.
