Average wait between Pearl Jam studio albums: 1 year, 301 days

Unless I fucked up the math (entirely possible… OK, extremely likely), the average wait between Pearl Jam studio albums has been a little more than one year, 301 days. That average will increase when PJ's followup to Backspacer comes out: As of today, it's been one year, 316 days since that album was released. Thanks to TwoFeetThick.com for the data. Stats nerds, feel free to check my calculations.
