It seems to me that there is not enough recognition for doing well in SubProjects aside from the badges.
Would it be a relatively simple matter to add Top10 sRanks and Top100 sRanks?
I think getting Top1000 sRanks may prove too simple to get but then newcomers might just love them for that very reason, and keep them coming back.
By all means give them a weird name so people don't guess what they are if you feel that you need to. I'd go as far as to suggest the Fonk, the TeraFonk and the ZetaFonk?

I suppose that while I am on, I might as well remind you of our old discussions of Team and Country related MiRBs and TeraMiRBs. I think tMiRbs and cMiRBs and possibly their corresponding Tera's are screaming to be heard ;-) With 10's and 100's as their thresholds instead of 100's and 1000's
