Are there any stats out there that state that leads contacted in the 24-48 hr best practices time frame (or less) see a higher lift in conversion rates of xx%? I believe I saw this at EE13, but can't find it in my slides or notes. Hmmm...

For reference, I'm referring to an SQO passed to sales following scoring (MQL) and telequalification (SQL) according to our internal process. I appreciate anyone's feedback in this area as I'm wondering if I'm crazy and imagined I saw this stat?! There WAS a lot to take in at EE13!
