I agree that the longer the board the more you loose so cutting to rough
length is useful.... I've also found that ripping to rough width for the
purpose often helps... with a bandsaw or handsaw, not with a table saw!
I will also note however that I avoid using boards as twisted as that one if
it is already at rough dimension. This as they typically do not stay flat
after jointing and thicknessing as the tension in the board changes with the
machining. The resulting board being some not so interesting and useful.

Absolutely this was good and I did not meant to down play his method and
as he mentioned, I think, the loss of material will be less if you get
the board to a near useful length to start with. The longer the board
the more you are going to loose.

I use my track saw to straighten edges on "flat" S2S lumber when ever I
buy that. And that is not what you are talking about, but a good tip
for removing the some of the cup using the BS.

Because I sell the lions share of my work I have pretty much gone to
buying S4S lumber. It saves me, and there fore the customer, a lot of
labor cost. Plus the sizes are predictable for yield.

Good info but one has to keep in mind that the board will be
considerably thinner depending on the twist, regardless of how you
accomplish flattening the board.

A track saw makes a lot of sense for that job...
I have a lot of rough cut Ash drying in my lumber shed at the moment that I
sawed with my Alaskan chainsaw mill. I've been debating how I am going to
get the first straight edge on the boards... and rip them to rough width. At
the moment I am leaning towards using my big bandsaw (36" throat and max
board is about 30" with the bark removed) with a power feeder and a tacked
on straight edge for the first cut. The bandsaw could handle even the
fastest feed rate of the power feeder. I'm thinking that with a pair or
three straight edges and a helper or two I could crank the stuff right out.
Ripping the boards to rough width would require just the power feeder once
the initial straight edge has been sawn... I'm leaning towards flooring with
a mix of 3 width boards (say nominal 4, 5, 6") but even at 6" that is a lot
of ripping!

yep, but he obviously did not loose too much since he was very
efficient. Certainly not to be used for 4s boards, as you are already at
3/4.
Granted when he does the top side the results of how much he lost will
be seen. But he lost less than I thought. I have often taken out a hand
plane to try to do the same. This looked much faster.
