How do you track of multiple tasks/projects with this technique? One calendar per task? A key/value mapping to replace the cross (e.g. a "G" for every day you go to the gym)? Simply merging them into one "meta" task? Or does it just not work for more than one task?

I since stumbled upon Giles Bowkett's variation whereby he uses a colour-coded horizontal line for each task. I like it. It emphasises the "chain" aspect and works well within the space constraints.
