I'll disagree, but for multiple reasons, and here is why.
I'll assume you mean Avis, as she has 61? max points, with next closest being Raiko/Koko with low 50ish. Sure, seems you missed a ton of points, and honestly, surprising amount, unless you continuously change who you interact with, in which case that amount seems perfectly fine. If you, however, focused most on the choices on her, and ended with that amount, then yea, you obviously made some mistakes along the way, and that's on you then.
If you, however, feel unhappy due to going for multiple girls, and only having on Avis that many points, and are feeling left out (missing content)... Then not only is that an expected result (as a non harem game) but also, incorrect (in current ep4 version!). The highest amount you need on Avis, to view ALL of her current content/extra dialogues, is 24. 24/61 total. That's not just low, that's imo generous, and I've been (for the most part) intentionally been generous with how many total points you actually need to view any extra bits, besides some rare cases (like Soo-Ah who is a side girl anyway).
Edit- Of course, however, in future Ep5+ trying to branch out to too many girls all the time, AND doing incorrect choices at the same time will lead to more and more missed content, as it's intended
