Question for Binding of Isaac fans

How high is your record for Guppy's Collar revives in a single run?

Mine is an absolute 0. I have been playing Binding of Isaac: Rebirth for a long time now, and have never been revived by it.

During the past 2 days I have even gotten both the Dead Cat and Guppy's Collar in a Lazarus run 20 times. I didn't beat any of those runs, yet not once during ANY of them did I get revived by the Collar. 50/50 chance, my ass.
