I suppose the "guess" comes from experience in doing such gearing with a
13-15-17-20-24-28-32 freewheel and 26/44/48 rings. What usually doesn't
get expressed about half stepping is that you simply don't have to half
step, or certainly not all the time ! What I'd do is simply treat it like
Half-stepping actually makes sense for rolling terrain where you shift at
least a couple of rear cogs at a time -- terrain with sharp elevation
changes, and use the chainrings to fine tune on flatter portions. But it
made more sense with few rear cogs; I worked it out once long ago and it
works
"A half step triple would work, like a 44/40/28 for example. The numbers
are off the top of my head, not a suggestion. Having the half step would
help split some of the large jumps in the cassette."
You guessed pretty well. The jumps in the 13-42 average about 18%, and a
44-40 is about a 9%
Thanks, all. I don’t have a lot of personal rear derailleur screwing around
experience. Usually IGH or one cog with 3x up front. I got the Altus and
extender in case and I’ll post back.

The wrap for a 1x Yankeebird is whatever the spread is for the cassette
alone, since there's no other ring there's no additional difference to
account for.
As for clearing the 42t cog, the only thing that matters is that the RD can
clear it alright. The "how" that is done, well there are
I have two bikes with Altus RDs shifting 11-42t 9 speed with derailleur
extenders, but I've heard of people squeaking by without one.

What about a 1x?
How do I calculate wrap for that?
I have two older bikes with the old trad 7spds cassette I’d like to replace
with 13-42. The Altus has a max rear cog size of 36 but if I only do a 1x
does it matter? Can I use the old derailleur, even?

As long as you're within the total capacity of the RD it could work with
one of those Wolf Tooth derailleur hanger extensions, called a Roadlink I
think. Others make them, but Wolfies and Wheels Mfg I know for sure use a
stainless steel bolt, while the other use aluminum. The Wolfie helps to
