You might be wondering what challenges that aren't Broad difficulty are? The answer for most of them is Narrow.
Narrow challenges have a range from 10% success to 100%. The challenge level has the chance of 60%. For every level above the challenge level, you get a 10% greater chance. For every level below you lose 10%, to a minimum of 10%. This challenge system is often used with non-main attribute challenges, like Respectable, Investigating..., Brass Ring challenges and you name it.
