I know that n either enters the final stretch of its sequence via:

5->16->8->4->2-> OR 32->16->8->4->2->1

However does parity of n have any bearing on final path through 5 or 32?

Finding 1 only 2^65-1 in test seems like an anomaly but what is the general ratio for results 32 or 5 for numbers say less than 1000.
