The rice we usually use:
Kokuho Rose California Premium Medium Grain Rice.
I don't know of any particular reason that we're using this over any other Kokuho Rose.

A. Filling the rice-cooker's bowl with water (to the appropriate fill line) and then adding the rice?
or
B. Dumping the rice in the cooker's bowl and then filling with water to the appropriate water line?
The two answers are NOT the same.
A uses a lot more water to cook your rice than
B does.
B is the correct answer here. The instructions that Zojirushi provides are not clear on the matter here.
Here's what I usually do (the long-ish version):
1. Measure out
1 green Zojirushi cup of rice.
2. Dump step one above into the Zoji's rice pot.
3. Leaving the rice in the zoji's pot, rinse the rice that I just dumped into the pot a couple times (draining all of the rinse water each time).
on the last rinse I try to get all the rice into the center of the pot.
4. With all of the rinsed rice centered in the bottom of the pot I add enough water to get to the
1 on the "white rice" scale of the inside of the bowl.
5. Cook it.
6. Eat it.
NOTE: By "green Zojirushi cup" I mean specifically that: it's the little green plastic cup that comes with the Zojirushi rice cooker. We've had ours forever. Maybe yours is a different color. The important thing here is that the actual measure of this green zojirushi cup is NOT equal to one standard US "cup".
Another NOTE: I mentioned it above, and TP checked your manual(post below): the color of the cup you should be using is described in your manual. It will make a difference (particularly vs. US cup sizes).

In the video below, note how they are using "Choice B" to cook the rice. They kind of gloss over the fact, but the rice is definitely in the bowl before they start adding water to the fill line.
