Your Lowest Centipawn Loss?
I do look at my centipawn loss, but only for general trends.
Against very weak opponents, it is much easier to get <10 centipawn losses, because the scoring pretty much doesn't penalize you for inferior moves once you're ahead by the equivalent of a whole queen, so if you win their Q early on (like you did in that game), provided you don't lose your Q at some point, you'll suffer zero centipawn losses even if you make a bunch of inferior moves in a totally won position.
Even the youtube NMs and IMs who livestream have centipawn losses of over 15 regularly in won games against decent opponents, so I'm not sure how meaningful it is once you're in the low teen range or below.
