X-Blocks
You schedule an hour for the report. The report takes three. Not because you’re bad at estimating — because everyone plans for the best case, and the best case rarely shows up.
X-blocks are how MakeTimeFlow turns an honest estimate into protected time. Tell us how uncertain you are with an x-factor, and when you put the work on your calendar, we reserve the time it will actually need — before the rest of the week fills in around it.
How it works
Give a task an x-factor (×2 if you’ve done this before, ×4 if you’ve only read about it), then schedule it on your calendar.
A task with x-factor 3 becomes three equal working blocks, back to back, starting at the slot you chose. The task itself stays on your list as the outcome you’re driving toward; the blocks are the sessions that will get you there. Finish early? Delightful — clear the leftover blocks and enjoy the found time. That’s a far better surprise than the usual kind.
A meeting with x-factor 2 works a little differently, because the meeting itself is already time on your calendar: the meeting counts as the first block, and one follow-through block lands right after it. That’s the time for the notes, the decisions, the “I’ll send that over” promises — the work a meeting creates. A meeting with x-factor 1 is just the meeting: no extra blocks, you’re saying it generates no work.
Either way the math is the same promise: x-factor × duration is the total time on your calendar. A 30-minute meeting at ×2 costs you an hour of your week — and now your calendar says so.
Where everything lives
Your lists stay calm. The task you created shows up in @today (or @next if it’s later this week, @later beyond that) — one line, the outcome. The blocks live where time lives: on your calendar, and in the table and outliner views if you want to see the full structure. You won’t find “xBlock 2” cluttering your @today list, but you will find your afternoon honestly spoken for.
Why your plan stays truthful
When MakeTimeFlow checks whether something fits your day, an x-factor task counts at its full cost — x-factor × duration — whether or not the blocks exist yet. The calendar, your capacity, and your gut all agree on one number.
Done, and done well
The Task Trust System is built on a simple idea: you can only trust a plan that tells the truth. Optimistic estimates feel productive at 9am and betray you at 4pm — the report half-written, the meeting actions never sent, the evening quietly donated to catch-up.
X-blocks let you be ambitious about what you take on and honest about what it costs. The work gets the room it needs to be finished properly — closed loops, not open tabs — and when you beat your own estimate, you get to feel it.
