Ricahrd,  thanks for correcting those values.
Actually I took some of the values from Jacques's email. E.g. he said:

15
- which takes 56 steps to reach a repeat, as I said in the sequence
- but no doubt there was a human error (probably mine) involved
- you are certain the answer is 55 ?

I've added three more sequences, A145077 - A145079, describing
other properties of the trajectory,
in case you would care to extend them too!
