This was posted before although the last time I could find a post suggesting this was back in 2017 when SOS chaining was new. It's been some years but I thought I would revisit the idea.
My suggestion is that the SOS calling rate statistic for wild Pokemon available in the Alola region could be displayed along with some of the other statistics for eligible pokemon. I don't have the exact link to a particular resource for finding these call rates, but they would make a good addition to the site I feel. A perfect spot where they can be incorporated into a Pokemon's database entry could be in the training section where it shows the statistics for EV yield, catch rate, base exp, etc. I know that it's been sometime since the generation 7 games were released although I think it would be a nice addition to the entries and for people actively playing/revisiting those games. Who knows, SOS may even come back in a future generation!
I hope I'm not being redundant with this post, but at least I feel I'm getting the point across. Thanks!
