I use kind 3 for follows and kind 10000 for mutes. Would be simple to cast a wider net though.

I agree: mutes count for more. The default params give a follow a weight of 0.03, as compared to a mute which I give a weight of 0.50. You can go to settings, change those params, recalculate and see the changes.

I picked those defaults after just trying a lot of different params and seeing which seemed to be the most useful in terms of stratification of the results.
