I'm not sure we hold that record yet, unless you're assuming we are in the play offs again this season? We made the play offs twice in a row under NW and we've made the play offs twice in the National League.
I think Grimsby just pip us for most promotions with 14, I think we have 13? Also, I think we have suffered 16 relegations so it makes sense we are now lower down the pyramid than when we started in 1888.
I think that makes us the second ranked yo-yo club, again behind Grimsby who according to wiki have swapped leagues 31 times in their history.
