Arlyn's "base speed" is the speed of the thrower themselves, and he uses this terminology properly. But I think the reality is more complicated than that. For example, I don't really buy his claim that "if you are running forward X miles per hour it will add X miles per hour to your throw."
Basically, what you want to do with your legs and body is to transfer forward momentum into angular momentum in your torso. That's what the x-step accomplishes. Arlyn's plant-heel-forward step is good for transferring your legs' energy into a hip pivot (so long as you can pivot off your foot well enough to relieve knee stress), which in turn whips the shoulders around. A 360 helps you to add more angular momentum than you can get with just the X-step, and anyways it's a straightforward extension of the X-step further back in time.
What you want to have happen, of course, is for the body's energy to become available at the same time your arm is reaching the region of maximum controlled leverage, and also at the same rate that your body can move through those positions and smoothly apply power to the disc. You don't always want to pour on this power all at once, a smooth power band is better because it is easier for your fingers to maintain a grip. How smooth? What you are seeking is "resonance" between the speed at which your arm positions naturally move and the driving force of your body. So getting this kind of resonance is really almost entirely about body positions and timing. But once it's achieved, you can get amazing results with little effort.
If you're more skilled, have the athletic coordination, and the strength, then you can handle more initial arm speed, and transfer energy into the disc from your body at a higher rate. Obviously you need a fantastic grip strength if you start pulling as fast as possible. It's just that it is very difficult to control this motion and get clean throws...in maximizing disc flight a clean throw is critical. I've seen some amazing long throwers in real time, such as Sandstrom, who simply possess super-human athletic skills. He can manage insanely fast initial arm speeds, and getting velocities onto the disc itself that are simply amazing (it sounds like the disc is tearing a hole across the sky).
Us ordinary individuals have to slow it down, and get the resonance working at lower speeds and slower rates of energy transfer between body and arm. When we try to speed up too fast, or apply too much force, our coordination and conditioning are not sufficient to keep up the resonance, so our throws actually worsen. This is why it sometimes seems like you throw shorter when you're really trying hard to throw further.
