I take it that you are referring to Bella's newborn strength? As in:
Alice >>> Bella (foresight)
newborn!Bella > Edward (newborn strength without newborn loss of control > slight speed bonus and a century of practice)
Edward > normal!Bella (speed, strength and experience)
Edward > Alice (faster and stronger and slightly more experienced)
I guess in a couple of years a cycle would require the introduction of a fourth, such as:
Alice > normal!Bella
normal!Bella > Alec
Alec > Edward
Edward > Alice
Of course Edward is somewhat redundant. Alec seems like he should be able to beat just about everyone who isn't Bella.
rationalist!Alec: "Hey, um... Boss... remember that time where my sister and I decimated the Romanians and allowed you to usurp their position as rulers of the vampire world? And you know how you maintain that power now because either Jane or I could singlehandedly destroy most covens? Well that chick is immune to both of us and yourself even while she is human. If you can recruit her you will get a new guard with a handy trick. If she turns you she could kill us all! A reward that would be a mere luxury and a risk that you cannot afford... do the math!"
Although it's not demonstrated in the books, Edward can in theory get around Alec. Alec's power works slowly and moves through space; by reading where it's going to be, Edward could just get out of the way. Jane's faster, so he can get gotten by her. Jane cannot, however, singlehandedly destroy a coven, because she's limited to one target at a time and not especially powerful physically.
In the vein of the Harry Potter and the Methods of Rationality discussion threads this is the place to discuss anything relating to Alicorn's Twilight fanfic Luminosity. The fanfic is also archived on Alicorn's own website <strike>(warning: white text on black background)</strike>.
Previous discussion is hidden so deeply within the first Methods of Rationality thread that it's difficult to find even if you already know it exists.
Similar to how Eliezer's fanfic popularizes material from his sequences Alicorn is using the insights from her Luminosity sequence.
Spoilers for the fanfic itself as well as the original novels need and should not be hidden, but spoiler protection still applies for any other works of fiction, except for Harry Potter and the Methods of Rationality chapters more than a week old so we can freely discuss similarities and differences.
EDIT: Post-ginormous-spoiler discussion should go to the second thread. (If you have any doubt on whether you have reached the spoiler in question you have not.)
