Partials
We often round for simplicity.
9.8 is a 10.
7.7 is an 8.
4.2 is a 4.
It’s easier this way.
And it’s tempting to start believing that the partials don’t count.
Four tenths? That’s not even half. It’s lost in rounding. Maybe not worth counting.
But do that 0.4 every day for a month, and it’s a cumulative twelve. And that’s not nothing.
There are always exceptions, but there are many areas were partials are plenty.
Or at least a start.
