The graph looks the same if I remove the top 5 user accounts (all greater than 1% of the data and between them totalling 39% of all way data) however the amount contributed by the top 10% of users (ignoring the top 5) reduces to 91.5%. So basically the 90/10 rule appears to apply for normal contributions made by the humble mapper. This is in line with what I see locally in my own patch.
