This has been discussed, and I think the answer was "no", last time I checked.
This was theorized to be because the exchange clearly took place in the early days, when Lori was still unquestionably married to Charles, as part of Chad's "flirting language", as it were. He wouldn't have (and in fact didn't, AFAIK) included his own family because Lori had not met them at this point; and so any "ranking" of them would mean less than zero to Lori, and thus would not be helpful in teaching her anything about the ranking system as a whole, or serving as a mnemonic or touchstone.
Largely this is because the entire scheme is as transparent as glass and "gamed" by Chad, in much the manner of your average sidewalk psychic offering psychic readings. Listen to the attractive woman talk about her family for a long time, with every appearance of flattering neutral listening; then parrot back a belief system that makes the people Lori already finds contentious, into particularly contentious individuals with horrible rankings like Charles; then-sympathetic individuals into "good, wholesome" categories (of course Chad is not going to start out at ground zero proclaiming an 8-year-old boy to be Damian); and along the way, some kind of meaningless "sacrifice" ratings for people Chad doesn't really care about one way or another, and whom he doesn't imagine impacts Lori's life a great deal (her grown stepsons with Charles, who were at that time not living under her roof, etc.); so can be treated as a careless one-off ranking that doesn't affect anything ("2.1D; 2.1L" - it's all gibberish for people whom Lori hasn't told Chad "how to feel about").
TL;DR version: all Chad's "ranking system" nonsense is, is confirmation bias in the manner of psychic and tarot readings. Lori has de facto told him what to talk about ("what I mention is important to me"); and what type of ratings to give people ("oh-so-coincidentally agree with how I already feel about them", unless Chad thinks he might need to, at a later date, "change his ranking" about someone Lori seems ambivalent towards.)
I also strongly suspect that if she hadn't been receptive to Reading #1 and Chad's advances, i.e., Lori's response had been to react hotly and negatively and say she loved Charles and thus his ranking couldn't possibly be true, Chad would have in fact backpedaled right on out of Lori's life, IMO.
