Estimate a piece of work

Estimate this: {{work}}

Known unknowns: {{unknowns}}

Break it into pieces small enough that each estimate is boring rather than brave.
Estimate each, then say which piece carries the risk and what would resolve it
cheaply.

Give a range for the whole thing, and say what would have to be true for the low
end to happen.

What to fill in

{{work}}

The work — e.g. sync user prompts through CloudKit

{{unknowns}}

What you don't know yet — e.g. whether tombstones need a separate record type
