I can't speak to what other people do and do not like. What I can say, is that at the reveal, they were using it.
I jcan't atest that was the exact same system and that higher scores required more points. And I hope it is not like this.
You can figure it mathematically. As previously stated, the PHB point buy equates to the Standard Array.
In the 'spent points' column, there were 27. Stats started as the standard array +1 Cha because that was the only thing currently in for Lightfoot Halfling.
Later, it shows Astarion in play.
