View-to-Follower Ratio VTFR
Average views divided by an account's follower count. It measures how far an account's Reels travel beyond its own audience.
Why it matters: A VTFR above 1 means Reels regularly reach people who don't follow the account, a sign the algorithm is distributing the content. It's a truer measure of reach than follower count.
Reach Consistency Index RCI
The ratio of an account's median views to its average views. It shows whether reach is steady across posts or carried by a few viral hits.
Why it matters: A high RCI means dependable reach on every post; a low RCI means a handful of outliers are inflating the average.
High Performance Factor HPF
How often an account's Reels exceed its own follower count in views.
Why it matters: It captures how frequently content escapes the follower graph, rather than how big a single hit was.
Use it for competitor research →Breakout Performance Rate BPR
The share of an account's Reels that beat three times its median views.
Why it matters: It quantifies how often an account produces a genuine breakout, not just steady content.
Find breakouts with Trend Finder →Engagement Stability Index ESI
How consistent engagement is from Reel to Reel across an account.
Why it matters: A high ESI means reliable engagement; a low one means one or two posts are propping up the average.
Baseline Reliability Ratio BRR
How close an account's typical Reel sits to its own baseline, reflecting the strength of its worst posts, not just its best.
Why it matters: It separates creators with a dependable floor from those carried by rare spikes.
Duration Payoff DP
Which Reel length earns the most engagement for a specific account.
Why it matters: Optimal length varies by account, so Duration Payoff finds it from the data instead of a generic rule.
Outlier Score
How far a single Reel beat its own account's median views, expressed as a multiple such as 10x.
Why it matters: A Reel at 10x an account's normal is worth studying. Measuring against the account's own baseline keeps small accounts' breakouts visible.
