Indeed.

I suppose something like "the number of distinct voltage changes per
cycle" might be a good first approximation of something to call steps
and to count.

In your example I would count something like "3" or maybe "2" or "4" -
I always have trouble with boundary conditions...

Heh. Programmers run into this all of the time - it's called "the
fencepost effect". If you have a 100' fence, and there's a post
every 10', how many posts do you need?

(100/10)+1 = 11
I used to farm.


Or this one: Imagine a short staircase, say to a "sunken living
room" or some such, of 3 steps:

There are only two steps. on the stairway. The others are landings

Three risers though.

Yabbut, that misses the point of the gag. It's easy to point at the three
risers:

.. ------------
.. | -- 1
, -----
.. | --2
.. -----
.. | -- 3
.. -------------

And, obviously, the middle one is #2.

But, while stepping up or down the stairs, the way most people count steps,
if you're going down, (to the right) you'd go:


.. ------------
.. | 1
, -----
.. | 2
.. -----
.. | 3
.. -------------

And count 3 steps. But if you're going up, which is right-to-left in
this exsample, you'd go:


3
.. ------------
.. | 2
, -----
.. | 1
.. -----
.. |
.. -------------

because where you started from is zero in either case, but step 2 is
different if you're going up or down.

With risers it is the same confusion.
