What To Sync Before You Ask Hydrogen
Sync is optional, but stronger web analysis depends on having the right windows and enough desktop coverage available to Hydrogen.

Sync the comparison windows you care about most first.
Coverage quality still matters more than raw quantity.
Hydrogen is strongest when baseline and comparison periods are both clean.
Start with the comparison you want
The best sync decision starts with the question you plan to ask later. If you want a week-over-week comparison, make sure the desktop app has captured those periods cleanly first.
Sync is there to support interpretation, not to replace the baseline that the Windows app builds locally.
What is usually worth syncing first
You do not need a giant history on day one. You need the recent windows that make your first useful prompt possible.
Your most recent seven to fourteen days of normal work coverage
Any days where fatigue clearly shifted and you want explanation
Optional wearable context if you want stronger energy interpretation
When not to rush it
If your recent days are interrupted, unusual, or incomplete, it is often better to track a bit longer before asking Hydrogen for strong conclusions.
