Dynamic input of dynamic block
Is the red distance going to be consistent all the time. If so why not move the arrow grips the back the distance it needs to be? Just like I've done in the attached drawing

Depending on what you finally need there are several ways.
One of them is attached.

What version of AutoCAD do you have? It may be a better idea to use constraints. Linear parameters can not start with a 0 length, they have to be a distance which is not 0

Test the attached block WCILL - pa1.

WCILL - pa1 only seems to have one grip for overall length .
That is what you asked for in post #4 ("I'll stretch by the right hand grip to a new overall length").
"Then what I need is to grab the left hand grip, stretch to the left and type in however much I need to stretch by."
What/where is my misunderstanding?
when I try and open it in the Block Editor I get ; error:
Try it again, here are no problems

Say no to the errors then copy and paste the block into a new totally blank drawing. Do you still get the errors?

I get errors
Ok I can (must 😞 ) confirm that. To open this block in ACAD 2022.1.3 shows the same problem here too.
I'll try to find how to avoid that - it will need a while ...

After recovering the file it works also in ACAD 2022.
To do that:
- Open a new file
- command RECOVER
- select the new uploaded file
You will get a message that 2 objects were erased (I don't know which objects, they have nothing to do with our block definition). => Now the block works well (here, I hope for you too).

Just to confirm ... you have given the linear parameter 2 the same point as start and end, so that it has a zero start length?
So you can have a zero start length for a linear parameter?
No and no. As @h_s_walker correctly wrote, a dynamic parameter can never have length = 0.
I tricked a little - if you zoom close to the parameter (and set the precision of the units to 8 decimal places), you will see that the start and end points are 0.000001 units apart. That's why I wrote above, test the block (whether it meets your practical needs and whether you can live with such a small inaccuracy).
Sorry for the small cheating, but first I wanted to understand how you want the block to work. Perhaps there are other ways (e.g. using constraints) to achieve your requests. I did not yet try ...
