The short answer
Gong analysed over 519,000 B2B sales calls and found that success peaks when a rep asks roughly 11 to 14 targeted questions on a discovery call, and drops back to average once you ask more. What separates good from average is not the count but the spread: average reps front load their questions like a checklist, top performers spread them evenly so it stays a conversation. The questions that move deals are about the customer's business issues, goals and consequences, not about features. On talk time, Gong's 2025 look at 326,000 calls found closed won deals sit around 57 percent rep talk time versus 62 percent on lost deals, against an original golden ratio of 43 percent talking and 57 percent listening. None of this is a script, it is a way to check your own calls against something other than your instinct.
