By what extent is Caedus more powerful than Vader?

Yeah nah, you still haven't provided a good scaling chain for Mara being with prime Vader beyond vague power growth with no quantification, let alone above him.

It never reached him. Even as he stood there waiting for it, the weapon changed direction, curving back towards the other end of the Sail Barge. Frantically, Luke reached out for it with the Force; but to no avail. The lightsaber continued its flight-

And came to rest in the hand of a slender woman standing alone at the top of the barge.

She Force-leapt five meters at Lumiya, slashing down right to left, two-handed. The stroke—all power, no finesse—clipped the Sith's headdress as she sprang back, slicing off a section. Lumiya's eyes widened, pupils dilated, but she was already whirling her lightwhip about her head. The tails crackled and hissed, missing Mara only because she threw all her energy into a Force push to slow them a fraction.
Mara didn't take that weapon lightly. It was the worst of both worlds, leather strips studded with impervious Mandalorian iron fragments and tendrils of sheer, raw, murderous dark energy. Mara drew her blaster and rolled under the hull of the ship next to her. The light-whip gouged through the durasteel with a shriek of tearing metal, filling the air with the smell of hydraulic fluid, and the spurt of liquid turned into a torrent that began spreading in a thick pool. As Mara rolled clear on the other side of the ship, Lumiya landed heavily on both feet and brought the whip down so close to Mara's head that she felt the rush of air on her right cheek like a breath. The crack was deafening.
Mara wasn't even thinking when she aimed the blaster. Lumiya's whip hand was raised to throw as much weight as possible from the back stroke. A puff of white vapor burst from Lumiya's shoulder, and she staggered a few paces.
Metal. Maybe I hit metal.
Maybe she had, because Lumiya teetered for a second but came right back. Mara sprang horizontally from a crouch and cannoned into Lumiya's legs with all the power she could muster from the Force. She hit solid durasteel. Blood filled her mouth but she couldn't feel a thing—yet. Clinging to Lumiya's knees with one arm, denying her the space to swing the whip, she brought her down like a felled tree before smashing her head into the woman's face.
And that hurt. Oh yes, Mara felt that. She'd caught not Lumiya's nose but the cybernetic jaw, and it cut deep into her forehead. Fighting on pure reflex now, part stunned, she killed the lightsaber blade for a second and held the hilt like a dagger, stabbing it down into Lumiya's chest before flicking the energy back on. Lumiya pulled to the side as the blade punched through flesh. Mara smelled it. She flicked off the blade to pull back again, triumphant.
I've done it. Dead. Dead, you—
But Lumiya was screaming, and that wasn't right at all. The scream seared through Mara's spinning head. It was more than sound. It was—
Mara scrambled to her knees to look down at what should have been a dead woman, and stared into green eyes that were utterly devoid of any emotion, and then the world darkened like an eclipse.
Maybe I'm the one who's dead.
Something hit her square in the back, pitching her forward onto Lumiya. Mara struggled to turn over without letting go of either lightsaber or blaster, but something coiled around her neck and jerked her backward. The lightwhip was still in Lumiya's fist, she could see the thing, she could see it, so what was around her neck, choking her? She felt as if she was flying backward at high speed, and then she hit something so hard that it punched every bit of breath out of her lungs and left her gulping for air.
A second or two was all it took. Mara lay trying to suck in air in painful, straining gulps, eyes stinging, and saw Lumiya's boots run past her face at a stagger, missing her by centimeters.
What's in my eyes? What's stinging?
She raised her hand to rub them and her knuckles came away red and wet. It was blood. The last thing she saw as she looked up was the orange sphere, that impossible Sith ship, soaring vertically into the air and extending webbed vanes like living wings.
