Hello again
I just suggested what I think is about the best video if you want to learn the easy way,
especially when it's regarding thinner stock.
I'm sure Custard has some posts touting the benefit of the flat bench.
Many don't suggest doing this, and might suggest a plethora of folks, say Richard Mcguire, or Grahams Face edge channel for example is kinda dedicated to stripping things back to the bare essentials.
Going back to the easy method,
should your stock be thin..you'll need something flat.
Guessing you don't have something like that, or you might have mentioned.
I think I suggested earlier that a melamine offcut might show up some high spots on the bench,
being so shiny would spin on a lump (and the fact your top isn't hacked)
Just make sure its flat I suppose, Frank Klausz reckons it's pretty flat when supported correctly.
The offcut would likely be a reliable enough surface to make witness marks on if unsure where
exactly ones timber is touching, should they not have an angle poise to see instead.
Used as is, providing it's sitting flat, or flatten any lumps with a few swipes with a scraper,
A fool proof way might be using graphite or crayon would make it real simple,
Crayon used below which shows up the high spots, i.e the only place needing to plane or scrape off,
Provided your stock isn't so thin and warped that it deflects, you can always be sure you will be able to shaving whatever colour crayon away with any thickness shaving and if not,
something is wrong.
it will teach you how little blade protrusion is needed, and how hungry a light setting can be.
You could do whatever ya liked with that info, i.e make precise beam to flatten the bench,
just do some rough spot work, or whatever,
It's just good for illustration regarding where you need plane...only,
This mindset will stop one from needlessly planing material away which doesn't need be planed,
instead always knowing exactly where one wants to stop and start, once flat,
then Charlesworth's stopped shavings to finish, as there could be the odd lump somewhere.

If you've watched that Cosman video, and make note of those
important tell tales I mentioned,
that's the lesson.
If I were to guess there might be quite a few intentional spanners thrown into it, and I do mean after the scrub.
(This all ties in with a cleat, and not a wide dog) to take things up a notch, as one won't
squirm with the thought of checking the work (which is always loose on the bench)
i.e can you see the far side of timber there, you would need be tall.
I reckon above is down to either a bump somewhere,
or perhaps technique, for the given material, i.e how much room for error, look up Charlesworth using his fingers as a fence.
If the stock is too thin to plane four sides before gluing up,
Your vice could be deforming the timber if quite thin, and the other face is twisted.
You might have seen a lash up version of a long grain shooting board, think Richard has a video on that, should you be that pressed for thickness.
By the way I'm doing this with a no4 smoothing plane, so I guess I'm making life harder for myself? It's all I have.

And lastly..
If you've got a flat surface, it's all you need, I've scraped some stuff flat with a no.80
Using the bench like above suits a wee plane, but might take a bit of effort to make something like the beams to check your surface to get started.
If you had a half decent long level, or could borrow one, it would be easier.
Sorry I couldn't make my writings more concise.
