- Minutes to review a co-worker's account6 to 10 minutes
- A person reviewing a co-worker's account checks finished work (fit, reason, timing, contacts). They don't research it again. 6 to 10 minutes allows a careful read. We replace this with our measured figure once we have it.
- Share of conversations that become a client15%
- Across B2B sales about 1 in 5 opportunities is won: 19% across 655,000 opportunities (Ebsta × Pavilion, 2025), 21% (HubSpot). 15% sits below that on purpose, since not every real conversation is a qualified opportunity yet.
- Lift from replying within the hour1.5× to 3×
- HBR found firms replying within the hour were nearly 7× as likely to reach a real conversation. We use well under half of that.
- Conversation rate when the reply is slower10%
- Yarlis estimate. The base the lift multiplies.
- Share of approached accounts that become a conversation1% to 3%
- Cold email benchmarks run from 0.45% (Belkins, 7.5M emails, 2025) to 3–6% (Apollo, 2026). Ours are researched approaches sent by a person, so they sit in between. A client measured 8% replies per accepted connection.

- Measured at a client, 2026.

- Worked out, not set: A = H × 60 ÷ m. Keeps results 1 and 3 in step.
- Approaches one person can send per month60
- Cautious on purpose: each is researched and sent by a person. A typical SDR sends about 41 emails a day (Bridge Group).

- OECD: US workers averaged 1,796 hours in 2024.

- Measured at a client

- Set by Yarlis
- Our working figure, set from the studies named beside it. We replace each one with a measured number as soon as we have it.
- Worked out
- Not set by anyone. It follows from other figures, as its formula shows.
