# Time Estimates: Finally Finish on Time
**The #1 reason projects run late?** We dramatically underestimate how long things take. Research shows we're off by 2-4x on unfamiliar tasks. MaketimeFlow makes this invisible enemy visible.
## Why This Matters
> *"I thought this would take an hour. Three hours later..."*
Sound familiar? When you can see realistic time estimates at a glance, you:
- **Stop overcommitting** - See your actual workload before saying yes
- **Hit deadlines** - Plans based on reality, not wishful thinking
- **Reduce stress** - No more surprise all-nighters
- **Build trust** - Deliver when you say you will
## The X-Factor: Your Uncertainty Multiplier
Be honest about what you *don't* know:
| Your Experience | X-Factor | Example |
|-----------------|----------|---------|
| Done it before | x2 | "I've written this report type 10 times" |
| Learned about it | x4 | "I watched tutorials, but never did it myself" |
| Totally new | x8+ | "I've never touched this technology" |
**Pro tip:** If you're tempted to use x8, break the task down first. You'll learn more and estimate better.
## How It Works in Practice
### Scenario 1: Quick Task
You estimate "Write email" at 15 minutes. That's your best guess, no multiplier needed. The outliner shows `15m`.
### Scenario 2: Familiar but Complex
"Build dashboard" - you've done similar work. Estimate 2 hours with x2 uncertainty.
The outliner shows `~4h` - your realistic window.
### Scenario 3: Breaking Down a Project
You create "Launch feature" with subtasks:
- Design mockups: 2h
- Build frontend: 4h
- Write tests: 2h
- Deploy: 1h
The parent automatically shows `(9h)` - the sum of its children. No manual math.
### Scenario 4: Top-Down Planning
You *know* the whole project is 8 hours based on experience. Set that on the parent.
Your children show individual estimates for tracking, but the parent's `8h` is what counts.
## Powered by Intentional Timers
This is where time estimates become *real*. When you start a timer from the outliner:
1. **Your estimate exists** → Timer starts with that duration (with x-factor applied)
2. **Children have estimates** → Timer uses their rollup total
3. **You just finished a timer** → Matches your working rhythm
4. **Nothing set** → 25 minutes (one focused session)
You click "Start" and immediately enter **Focus Mode** with the right duration. No setup friction. No guessing. Just flow.
Every completed timer builds your history - creating a feedback loop between planning and reality.
## High Performers Use This To...
**Plan realistic sprints** - "I have 6 hours of deep work time this week. These tasks total 5h 30m. Perfect fit."
**Negotiate deadlines** - "This looks like 12 hours of work. With my other commitments, I can deliver by Thursday."
**Protect their energy** - Seeing `(4h)` on a task prevents the "just one more thing" trap at 5pm.
**Stay in flow** - Start working in seconds, not minutes of configuration.

## Advanced: Learn From Your Patterns
Over time, your timer history becomes a powerful teacher. MaketimeFlow tracks:
- **Actual vs. estimated time** - See where your planning assumptions break down
- **Focus patterns** - When you do your best deep work
- **Completion rates** - Which types of tasks you consistently underestimate
Use the **Analytics** view to spot trends. Many users discover they underestimate creative work by 50% but nail administrative tasks. That insight alone can transform your planning.
The goal isn't perfect estimation - it's *calibrated* estimation. Each week, you get a little more accurate. Projects that once felt chaotic become predictable.

*Time estimation isn't about being perfect. It's about being less wrong - and that small improvement compounds into projects that actually finish on time.*
