The stats always show a rough percentile of rank - For eg 98% or 67% etc. But that is not enough as it doesn't give an insight on how am I performing compared to others. 98% might be a good percentile score if it's in comparison to 100k (or 100,000) people but it might be bad if it's compared to 100 people.
So can you provide accurate ranks along with the percentile score provided? For eg -
Your rank is 98,000/100,000
Also, Brilliant is open to people of all ages and professions, from a rocket scientist to primary school student . While I do agree that age doesn't matter in solving problems, age-wise grouping of percentile would be helpful too.
