2 min readAn original planning guide. Use the linked primary documentation for platform details and the supported procedure for your environment.
Identify each dataset
Record the source, date range, page or origin scope, device grouping, and available coverage. Keep missing data explicitly marked.
List environment differences
Compare network conditions, hardware, cache state, content variants, and user interactions where the reports provide that context.
Match the question
Use lab tools to reproduce and investigate a specific behavior. Use field evidence to understand what covered real visits experienced.
Report practical limits
Explain the finding and its uncertainty. Do not turn a single run, sparse sample, or aggregated origin result into a claim about every visit.
Worked scenario
See the plan in practice.
A lab test opens the homepage once, while field INP includes later interactions across many visits. Those observations answer different questions.
