2023-02 February: now a usual day is: 25m pomo for morning pages (usually ~7:30 AM); 30m meditation; then 5-6x 55m pomos, stepping down if focus is poor; finishing ~2:30–3PM (2024-04 April update: still doing this, working well)
2022-11 November: now using 55m pomos when starting before 10AM; 45m before noon; 25m after, following data from Project - pomodoro experiment; practically speaking this usually means my morning goes: 55 55 45 45 45 25 25 [25] (~5.5hrs active time in ~6hrs of clock time)
Switched back to 25m/5m pomos in Jan 2022 as part of Program - finish my workday in the morning; focusing on longer contiguous blocks (6hr instead of 4hr, no long breaks) and higher-quality deep attention on harder tasks rather than trying to optimize efficiency
