When jointing on a router table, the fences are *supposed* to be mis-aligned.

Correct!

The out-feed fence is supposed to be about 1/16" closer to the operator than
the in-feed fence.

Correct!

The bit is then aligned flush with the face of the out-feed
fence.

Correct!

I'm suspecting the two fences, outfeed and infeed, are not parallel, despite their being offset. They are not exactly coplanar. They need to be offset and they also need to be perfectly coplanar.

I suspect your hand movement is giving you a misjudged idea of why you are having the bump. It's not your hand movement that's the (main, if at all) problem. Check to make sure your fences are coplanar, despite their being offset.

As to a dedicated jointer, both infeed and outfeed tables are normally parallel to one another. They need to be perfectly parallel. They are also offset, depending on how much wood thickness one wants to remove, and the infeed table is lowered by that much.

With the outfeed table lowered well below the infeed table (and cutter head), one can purposely joint an arch, along the edge. In this case, the tables still remain coplanar.

The arch can also be done if the back end of the outfeed table is lowered relative to the front end, i.e., angled, hence, the two tables are no longer coplanar, since the outfeed has been angled. This technique is rarely used, except for larger than "normal" arches, because it's sometimes difficult to realign the table, perfectly parallel, to the infeed table. Once set, one should not mess with the alignment (coplanar) of the tables.

Again, check that your fences are coplanar, despite their being offset. Whatever straight edge you use for this gauging, double check that its edge is, in fact, straight. ....and the offset is what it's suppose to be all along the whole length of the outfeed fence, relative to the infeed fence. Relative to the infeed fence, if the offset is not the same all along the full length of the outfeed fence, then your fences are not coplanar.
