I’m not sure I was doing exactly what they describe, not sure I was tapping as much as I just wasn’t staying regular and drifting +/- 5km/h to the point I got a couple complaints about it. I never realised it before and after that worked on keeping steady and it came quickly.
It’s why the paid services are successful. Another option I heard about is to have a “data buddy” so you both install a NAS at each other’s house, sort out access etc and that’s your off-site.
