309 followers puts this account in the Nano tier (under 10K followers). This is an asset score — how many people the account can reach — and it never moves based on how well the posts perform.
Weight 0% · log-scaled followers: L = log10(followers); L≤3 → 5–25, 3<L≤6 → 25 + (L − 3) × 20, L>6 → 85 + (L − 6) × 15, capped 100
log10(309) = 2.49, mapped as 25 + (L − 3) × 20 across the 1K–1M range (1K=25, 10K=45, 100K=65, 1M=85, 10M=100).
Engagement rate 22.68%, at or above the 8.00% top-decile rate for accounts with under 5K followers. Typical is 4.00%.
Weight 35% · piecewise-linear percentile curve for under 5K followers: 0%→5, p25 2.00%→30, p50 4.00%→55, p90 8.00%→85, 14.40%→100
Engagement rate 22.68% mapped onto the under 5K followers percentile curve (0%→5, p25 2.00%→30, p50 4.00%→55, p90 8.00%→85), measured across 12 of 12 sampled posts with visible like counts.
Engagement Quality
Not measurable
Weight 25% · comment-to-like ratio = avg comments ÷ avg likes × 100, mapped 0%→5, 0.5%→30, 1.5%→65, 3%→90, ≥5%→100
The typical post carries 2 comments, below the 5-comment base at which a comment-to-like ratio is statistically meaningful. One or two reactions expressed as a percentage is not a measurement, so the weight is redistributed rather than scored.
Posting cadence 0.03 posts per week, below the 1-per-week floor most active accounts clear. Gaps between posts vary by 1.46× the mean gap of 221.0 days — under 0.5× reads as a dependable rhythm.
Weight 15% · 60 × (1 − clamp(stdev(gaps) ÷ mean(gaps), 0, 1)) + 40 × cadence factor (0/wk → 0, 3/wk → 1.0, 3–7/wk → 1.0, 14/wk → 0.6, ≥21/wk → 0.3)
regularity 0.00 (1 − stdev 322.8d ÷ mean gap 221.0d) and cadence factor 0.01 from 0.0 posts/week (0→0, ramping to 1.0 at 3/wk, flat 1.0 through 7/wk, tapering to 0.6 at 14/wk and 0.3 at 21+/wk).
Content Performance
63 /100
The best post in the window drew 2.0× the median post's likes — 1× means no post ever breaks out, 3× or more means the account reliably produces outliers worth repeating. 50% of sampled posts carry both a caption and at least one hashtag (a well-kept feed is usually above 80%), across 2 distinct formats.
Weight 15% · 60 × upside score (top-post likes ÷ median likes: 1×→30, 2×→60, 3×→80, ≥5×→100) + 25 × caption-and-hashtag share + 15 × format mix (1.0 if ≥2 product types, else 0.5)
upside 1.98× (top post 122 likes ÷ median 62) scoring 60, enrichment 0.50 (caption + ≥1 hashtag), format mix 1.0 (2 distinct product types).

This is the first recorded audit of this account, so there is no observation window yet. Instagram publishes no follower history — Instapect measures growth by comparing snapshots it takes itself, and the trend appears from the second audit that is at least 7 days later.
