I think it's important to have the distinction between precession and Life After Death because they are mutually exclusive events: precession is refers to the balance a Beyblade exhibits after it has begun to wobble, and LAD refers to the ability of a Beyblade to continue spinning even after it has fallen over. They both refer to "continuing to spin when a part doesn't have enough energy to maintain stable", but they don't happen at the same time, and something with good precession won't necessarily have good LAD.
How do you measure a Beyblades "Ability to continue spinning at low rpm/energy"? Isn't it through both precession and LAD?
The thing is that good precession can substitute for good LAD or supplant it entirely. I agree that precession and LAD, at least without redefining the latter, are two distinct things, but I feel that they aren't nearly as relevant as something that encompasses them both (and any other similar phenomena) would be.
As for how to measure that, well in plastics you just get a left and right sg, two wide survivors/wide defenses and a pair of AR's that perform roughly evenly when one is in left and the other in right, build the combos, launch, repeat x amount of times and see who comes out on top. This is because it's that ability to continue spinning at lower rpm (i.e. using energy more efficiently) that determines the victor of a spin stealing matchup as long as the collisions aren't causing major interference (recoil/destabilization etc), especially because height-based destabilisation isn't all that relevant to plastics. Harder to do with MFB for various reasons - more destabilization, recoil, limitations of opposite spin parts, etc etc, but that doesn't mean we should continue using a needlessly complex dual-measure system for it.
@AZL: There was a decent discussion of this from a long time back. The short answer is Traction (and also rubber doesn't always make things faster (look at RS)), and I'm pretty sure if you search for traction you'll find it. Also, please use the edit function rather than making multiple posts.
Ingulit: He's talking about movement speed, not rotation speed. People seem to forget that movement comes from the energy of rotation, more traction allows more of that rotation to be converted to movement around the stadium. 'swhy cars have rubber tires and drag racers spin their wheels to get them warm and more grippy.
@Shining God MS: While I am neither Admin nor Moderator, if a beyblade stops, it loses the match. It being able to be spun again would almost certainly be due to decent life after death, but for our purposes this is completely irrelevant. Also note that Life After Death is not a "have or have not", it's a property of all beyblades, they just have differing amounts (some have almost none, some have a load).
