Any suggestions?
I still think that two meaningful digits are enough for an EXPLAIN. We usually need to estimate the tuple set's size, not a precise number of tuples or groups. And definitely, not an arbitrarily chosen two digits after the point. So, IMO, good examples may look like the following:
50%, 5.0%, 0.00051%.
