I get the feeling Artie is using a workmate.
Learning to plane on flat surface is self explanatory, and should one be thinking of doing a course rather than sorting out a reliable surface to plane on sounds a bit counterproductive to me.
That video I linked is probably the best you will find, even though it seems Rob is a little rusty not going from corner to corner straight away to deal with the twist ?
His older publication on the matter is a better watch, put it this way, try finding a better video for nothin.
95 percent of everything else on the tube (regarding planing something not pre machined) has all sorts of bad habits
Two main ones which comes to mind are...
Clamping a board to plane its face side, only necessary if you're Peter Follansbee,
and planing whilst the work is un-supported.
If you were to go by those rules, that would eliminate most of anything which would be misleading for someone who
wants to
Maybe it's a matter of teach my why a flat surface is so important?
I'll give it another shot as to why, as I'm back home now.
I'll try and reason why these things mentioned are bothersome, the questions are a bit backwards for me trying to structure a photographical answer.
Hopefully you have a straight edge of some sort, as long as the work is.
I'd like to have the bench/planing beam what have you, this flat.
Then you can utilize the techniques like sighting easily and accurately, and to a finer extent candle the edge with a good lamp behind the work.
(lampshade is 7.5" old school angle poise, seen similar "terital" in ikea for a tenner, but might need a larger shade made for them)
Still not as good, but a good start for now, you need swing to see
underneath both sides of the work.
See a good bit of material to be removed from the ends, can't plane into a hollow with a flat handplane, as it's not a belt sander.

Depending how long it takes, or how good/long of a level you might have already,
you will eventually get to the point where you have one reliable surface .
With a pencil gauge, or vernier calipers to find the lowest point,
plane the timber so it's parallel along the length.
Do the same with a second beam, these are parallel in length as to be flipped around
to make sure there is no matching errors.
Now you know you can trust the straight edge/timber beams and dress the benchtop/planing beam flat.

With something flat, techniques like pivoting, knocking, rocking, burnishing or marking using the surface or straight edge.
Charlesworth will show you these if you look
I think it's worth noting that a plane set for a light cut, might not be as light as one thinks it is.
To find out what a smoother should be advanced to, one could try this cheat using graphite, crayon, or even just by rubbing the timber against something flat.
It is self explanatory that the high spots are in contact with the bench,
and the rest of the timber won't sit flat until these areas are removed.

A good lamp makes this simple, beware that those on the bay have very misleading measurements

So hopefully the point has come across that you wouldn't be wanting to be planing very accurately on a surface like the bench below.
Anyone with such a bench with cut marks and chops in it, obviously isn't wanting to do precise work by hand.
A tell tale sign IMO
All the best
