I'm not a fan of using fish to cycle though. It subjects them to high levels of ammonia and nitrites during the spikes and that does nothing good to them. Many years ago, that was kind of a standard practice, but it is pointless now , IMO.
I do think the 4 ppm ammonia thing seems a bit mystical though. Seems like it would be totally different for a 20g versus a 120g versus a 240g. If the BB is present and working, adding two fish to a small tank just has to be different than adding the same two to a big tank.
