https://en.wikipedia.org/wiki/List_of_WWE_ChampionsScroll to the bottom to the Combined Reigns section. Jinder will be surpassing Sycho Sid and Jericho (knocking Y2J out of the top 30) this week and could potentially surpass Flair, Reigns and perhaps even Eddie Guerrero, Edge and Styles.
They may even be even crazy enough to let him hold onto the championship even longer which would mean he'd have more time with the strap than Miz and Sheamus. Though I would be very surprised if he came close to Rollins or Undertaker.
