Yes, but the spreadsheet is configurable to be whatever cycle length you want, they just recommend 30 minutes as a type of standard, try this first, length. The 30 minute work cycle is 100% focused, with a 10 minute break that I usually get up and do some sort of movement, whether it is a run break or stretching or just going outside to look at the trees, and some type of offline processing happens here where my mind is still "into" the current problem space. It helps break things down into achievable units of work, you get a nice spark line chart to measure if you achieved your goal and it gives you a fast feedback loop on whether or not you are creating achievable enough cycle goals. Once you do a work marathon this is all much easier than it sounds. I do recommend trying one out. When I get to doing this every day for 8 hours a day I am confident I will be 5x more productive than I usually am. This is a compounding time investment.
