Eternal does, based on basic laws of physics, have a lower spin time. Human launches aren't consistent. The POM free spinning construction of Bearing makes it spin much longer.

It's not launch variance that's behind this. I did 10 launches with each and averaged them to iron out any particular good or bad launches. Even then the variance wasn't nearly high enough, with both drivers being at most 8 seconds off of the average, with most of them falling within 5 seconds. This means that Bearing's best (~1:33) is still worse than Eternal's worst (~1:48). Variance alone is simply not enough to cover the 31 second gap between their averages even in a best case scenario. If the variance isn't high enough, there's clearly something that you're overlooking here that would cause it, no?

Here's a theoretical for you: The same combination on Bearing and Eternal both have the exact same amount of momentum, both of them spinning slowly and starting to precess (that's the scientific word for a top that's spinning too slow and is starting to tilt over). Who wins? Bearing does. It's not even close. Bearing can simply stay upright for so much longer and loses less spin late into a match, as the bearing is so efficient at such low speeds. The issue is that this only works at low spin velocities. At higher spin velocities, you start to run into a pretty serious problem with Bearing.

Free-spinning drivers like Bearing are simply a shaft in a hole, with the shaft spinning freely. This hole is slightly larger than it needs to be for the shaft to fit, since humans can't yet build a perfect hole that fits the exact diameter of our shaft. This means that the shaft is allowed a small amount of space where it can move around. While the bey has a large amount of energy, all the slight imperfections of the bey makes the shaft shift in its hole and can cause Bearing to shudder and move around as it struggles to regain a proper balance, and I've seen Bearing ride the tornado ridge from this effect. On top of that all of this, wobbling forces the bearing to start spinning around quickly as the shaft slows down from its contact or hits the horizontal limits of its motion, and the bearing isn't very efficient spinning that quickly and drains stamina rapidly as it tries to cope.

Although this wobbling caused by the bey's imperfections also applies to the stationary "shaft" of Eternal, Eternal is firmly locked in place and therefore can't shift around the same way that Bearing does, which means it balances better at higher spin velocities and maintains a smoother, less interrupted spin. All of this coincides with what I've seen during my tests: Bearing will slow down rapidly then stay spinning for an incredibly long time at almost no spin, while Eternal spins quickly for so much longer while being far steadier until it slowly runs low on energy and starts to precess.

That's our missing piece here: Bearing cannot handle the intensity of a hard launch without being terribly inefficient, while Eternal can handle those high spin velocities so much better, and it turns out that being able to maintain a higher spin velocity for as long as possible results in a higher overall spin time than losing most of your momentum early and then riding it out at a low spin velocity.

Wait, is your Bearing worn?
Mine isn't and spins longer than Eternal.
But wear makes it more aggressive and it loses stamina faster
