Why did you choose this stacking method? I've read about it—isn't it for those who don't have a tracker?

There's this approach called Lucky Imaging, where they take exposures of just 1 second each and shoot for hours. To avoid accumulating hundreds of millions of files, they stack the frames in real time, usually with rejection of blurry frames, so the final image isn't blurred by the atmosphere.
