Maybe you should include a few more bands in your stats, such as one with say 1 sp (above the grant) to eliminate unactive accounts. Also the 100-500 and 1000-5000 bands are much more difficult to breach than the others.

if you ask @abh12345 he can do it more precisely. I can include it for the next perhaps but I did it this way for consistency sake.

People with over 100sp begin to have a meaningful stake and people with over 1000sp would be considered investors and can have some influence.

Yep, and the platform expands, those with 1000 are going to seem very rare and powerful.
