At Yessheet (www.yessheet.net), we've discovered that spreadsheet-calculated viral coefficients (K-values) transform referral programs from guessing games into predictable growth engines. Our breakthrough came when analyzing the "Invite 3, Get 25" campaign which achieved an exceptional K-value of 1.9 - meaning each participant generated nearly two new users.
