Each soft reset takes one minute and three seconds if playing optimally which I most certainly wasn't frequently, although starting at 16384 resets (twice the odds) I started dual hunting on a copy of Black 2 as well, so you can effectively cut every SR's time in half after that. I don't remember when I started, but I always would watch TV shows whenever I would hunt, so here's all the shows I went through:

Gurren Lagann

SpyxFamily (season 3 hype!)

The Sopranos

Parasyte: The Maxim

Kaguya-Sama: Love is War

Last Week Tonight seasons 1-3

Assassination Classroom

King of the Hill seasons 1-7

And finally, the little bugger showed up during the second-to-last episode of Horimiya!

Prior to this, my longest hunt was somewhere in the 16000s.
