So I decided to chain again just to keep my skills fresh and I was going through shinies just to c if any caught my eye. Well I came upon shiny teddiursa . This little guy is looks awesome don't care for ursaring but I just had to chain it. So I get to 34 and my first patch appears then after reaching to 40 I finally start reseting and this had to be the most I ever did besides eevees. I managed to get 5 using over 300 repels jus alone on resetting.
Honestly when I did the eevee's I started resetting at 35. With the low percent count u want to be very careful to be safe and waste all that time just reset at 35. It may tAke awhile but it's worth it.
