Ah, yes. You're right. I was thinking about it on a whole unit, vote, and dollar basis. The divisibility is obvious and I can't believe I overlooked that. Sorry for inadvertently wasting your time, but thank you for responding.

I've been very curious about this. How many places does the block chain calculate out to currently and is that expandable as prices rise? I see more SP decimal places on some third party interfaces that don't show on the current site.
I feel that minnows even now should be rewarded in whatever small fraction of SP they earn from rewards, even if it doesn't meet a .01 payout threshold. Seeing progress is important for user retention, and would frame rewards as more of a points system redeemable for currency, fostering a more long term - less immediate mindset.

I have been assured by those folks at GitHub that the minnow math is being done in the code, just not in the UI.
And my wallet seems to reflect that.
Even if your curation rewards don't get to .001 the math is still being done and your account is getting credited, I'm told.
