Was going through vision preflop and when folded to in SB it suggests to rfi ~35% and cc ~15% (numbers might be slightly different)

I tried going through different hand groups to see if I could find any patterns as to what hands prefer to call instead of rfi in this spot, but struggled to find anything that made sense. It seemed like most hand classes were mixing?? not sure if I was looking at it right. In most preflop plo spots vision seems to have distinct groups of hands which prefer to take one action over the other, so I found this surprising and thought I was maybe just missing something. I play mostly in timed rake live games that often get shorthanded, so would be helpful to be able to use this strategy instead of just rfi everything like I would in a hi rake game.

Anyway, if someone has insight on what/why vision is doing here I would greatly appreciate it.
apologies if there is another similar thread or if there is a separate forum for vision related posts, if so i didnt see it.

thanks
