I originally replied thinking you were referencing the cheating Sneacail, but in re-reading it looks like it was about the lying.
I don't think a person gets points for improving the quality of their lies, but that's just me. But if I were you, after 20 years of being around a liar, I might care that the lies are getting better. I'll defer to your experience, as I haven't had to walk down that path. Sounds more like optimism than objectivity, though.
