What they do is a case by case basis. Might point out that 82 ABs is double the sample size of 42. Still small but still double. My statements are based on my experience going back to childhood which ahhh, was just last year. Yeah that's right.
Almost told how old I was. And based on what was explained in various communications in sources like the Strat Fan Magazine. Printed no less. Not that I am old enough to have been an original subscriber and read them when they came out, cough cough.
Anyway if the player has a track record they will sometimes blend the current season numbers with past season numbers to smooth them out. So hit .500 in 16 AB verses LH pitching when you have a career .200 BA against lefties and that card will get suffer significantly against lefties. No track record and they may blend a little L/R stats so it is still good but not so one sided as the pure numbers might appear to call for. Bottom line they look at the situation and make a subjective judgement call. And when things get subjective consistency may be just an illusion, the main reason I like math class and comptuter programming more than english and literature.
