Sorry about that, I didn't mean exactly half or anything like that.
Still, I don't feel that it's wrong: Even on rereading, my phrasing seems to address GP's misunderstanding in an immediately accessible way. Which is better, a complicated answer that leads to proper understanding (if you understand it) or a simple answer that solves the acute misunderstanding (and leads to a smaller misunderstanding)? Both kinds of answer have merit IMO.
