48 is for the 75:25 probability.
I did have the wrong number of years for 50:50 though, it's not the 10 I stated. This problem is the reverse of binary doubling, and I knew 10 bits are a needed to get to 1024, and my brain just sealed out thousand and million. It takes 20 bits to get to over 1 million, so 20 halvings from exactly 1 million should get you to less than 1.
