In some ways, it's the fear of facing that guilt that makes the "chain method" work so well. The tricky part, when you miss a day, is figuring out a way to cope with that guilt and frustration without letting it undermine your efforts in general. Especially if you miss multiple days in a row, for instance. Which is hard, because that requires a lot of motivation--which is one of the things the "chain method" is meant to enforce. So in some ways, it's a chicken and egg sort of problem. You just have to hope that you've done it enough that, when you wind up facing a missed day, you've built up your motivation for the task enough to get back into it.

Which is exactly why it doesn't work.

I'll go with "It works until it doesn't."

That was my experience with calorie tracking in MyFitnessPal. Did it for months, had a solid streak, then skipped a couple of days while traveling. I've done it on and off since then, but never got reliably back on the tracking wagon.
