Bicep curls while sleeping. Why wouldnt this workSrs?

I could be wrong, but the scale seems to be measuring "muscle activation" as how much of the lift is done by a particular muscle. If I'm right, that means that to do a concentration curl, 95% of the force is exerted by the bicep muscle. Presumably the other 5% is the forearm/wrist.
But that's a very incomplete picture - because it doesn't mean concentration curls will give you the biggest biceps. It means that concentration curls will NOT improve much else.
Take cable curls for instance. Cable curls have a "muscle activation of 80%" - so if you do concentration curls with a 20kg dumbbell (@ 95% muscle activation). Then you get the same effect from doing a cable curl with 23.75kg (@80%)
It's just that with the cable curl, you also work some other muscles a little bit (the other 20%).
So really, the chart is only effective when you compare the weights that can be achieved with different exercises. If, for example, you can cable curl 25kg but only concentration curl 20kg for the same number of reps, then actually the cable curl will be more effective.
You'll find your solution to what's "best" for getting big biceps within your last sentence, i.e. through isolations. If your aim is to stimulate superior growth in a targeted muscle, (here we're talking biceps), then isolation exercises would be the "best" that you'd want to look for. When I refer to an isolation exercise, I'm not referring to bent over/seated concentration curls (even though that is classified as an isolation movement). By isolation, I'm referring to more than just the exercise, I'm referring to how the targeted muscle is affected by the way you choose to do that exercise and where you choose to place it in the order of other isolation exercises you're performing for that targeted muscle.In that manner I guess it's actually useful. Letting you know how to structure those workouts to fatigue the right stuff in the right order.
But again, this measures isolation, not what's "best" for getting big biceps
From what I see, the brachialis is the contributing factor to the results of the tests.
All things being equal, the barbell curl is the real deal, along with chin-ups
biggest my arms have been ,,19.5 if you want big arms you want to get big all over, and the heavy compounds do the trick aka heavy rows^ nope
