Instagram Post Sorter: Count vs Date Range

Choose Count for comparable sample sizes or Date Range for a campaign window, with sampling bias, stop rules, and loaded-set limits.

Choose Count when you need approximately equal sample sizes across profiles. Choose Date Range when the question is about a campaign, month, quarter, or publishing period. Count can cover different time spans on different profiles; Date Range can produce very different row counts. Neither proves complete history.

Decision table

Research goal	Choose	Suggested input	Main bias	Actual stop	Verification
Similar-sized shortlists across profiles	Count	25 or 50 each	Different publishing frequencies cover different time spans	Target, Stop, no new unique cards, or error	Record actual `scanned` and displayed counts
Review the last month	Date Range	1 month	High-frequency profiles contribute more rows	Oldest collected date reaches cutoff, Stop, or no new cards	Check oldest/newest dated source posts
Get a reviewable candidate set	Count	25/50/100	Older content is excluded	Target or early terminal state	Report the actual set, not only the target
Compare a quarterly window	Date Range	3 months	Timezone, missing dates, and page coverage affect edges	Cutoff or reachable end	Record run time, range, and missing dates
Explore as much as the page offers	All	All	Highest risk of a completeness claim	No new unique cards or run ends	Label `loaded set; not full history`

Count options are 25 / 50 / 100 / 200 / 1,000 / All. Date Range options are 1 week / 1 month / 3 months / 6 months / 1 year / All. Count targets unique posts observed cumulatively; Date Range compares the oldest collected parseable date with a runtime cutoff.

Same count does not mean same period

If profile A posts daily, its latest 50 rows might cover seven weeks. If profile B posts weekly, 50 rows might cover nearly a year. Count improves row-count comparability but mixes time spans. It is the right choice only when the goal truly is “take the same number of candidates.”

Same period does not mean same count

In one month, profile A may expose 60 posts while profile B exposes eight. Date Range preserves the time question and accepts unequal samples. Report both the requested window and the actual loaded count.

Control definitions

Control	Exact INS Sorter meaning	It is not
Count	Target for unique posts observed in this run	Mounted DOM count or account total
Date Range	Relative cutoff computed from runtime time and the oldest collected date	Arbitrary From/To or official report window
All	No preset count/range target; continue to the current page's terminal state	Complete-history guarantee
Stop	Request an end during loading and retain the loaded set	Delete results or prove completeness
`target-reached`	The run finished at its target or current reachable terminal point	Proof that every external post was collected

One month uses calendar-month subtraction, not a fixed “30 days” label. If dates are missing, the run cannot use those rows to prove the cutoff was fully covered.

Verification workflow

Write the goal: equal-sized candidates or one time window.
Choose Count for the former and Date Range for the latter.
Pick a boundary you can manually inspect; do not default to All.
Record start time, target, profile URL type, and sort field.
Watch progress and use Stop when the set is sufficient.
Record actual scanned, current candidates, and oldest/newest dated posts.
Report target, actual set, early-stop reason, and missing-date count.

Limits

The workflow only reads cards the supported profile exposes to the current browser session. It does not bypass login, challenge, private access, or layout limits. Virtualization can make cumulative scanned higher than the currently mounted and sorted cards. A date range can end early when no new unique card appears.

Other pages describe exports, APIs, owner analytics, and custom time windows. Those architectures do not become INS Sorter features. INS Sorter produces a temporary grid view, not a report or persistent dashboard.

Choose the boundary, then run

After choosing the input boundary, start from the INS Sorter product page. The planned custom-date sibling is not public, so this page does not link to it.

Frequently asked questions

Should competitor profiles all use Count 100?

Only if equal-sized candidate sets matter more than equal time spans and you can inspect that volume.

Does 1 month mean exactly 30 days?

No. The current runtime subtracts one calendar month from the run time.

Does All return complete account history?

No. It removes the preset target but remains bounded by current-session loading and terminal conditions.

Can a stopped result still be used?

Yes, as an explicitly labeled partial loaded set with its actual count and stop reason.
