Haha, well, thank you for the kind words, first of all! Glad you've enjoyed the other work 'e done too.
There 100% is a discrepancy with the number of CGs. Some new folks might not be aware, but CaptainGerBear isn't the artist I started the project with. He didn't step in until Harold's route was nearly done, and all of the other routes were well into their Day 20+. His consistency in producing art is far better than my original artist (I had maybe 10 or so CGs before Ger joined).
That being said, a lot of the older days on the original 5 characters lack art because... well, I didn't have someone doing art consistently then. We're filling in art through older days slowly though! Whenever I get the chance, I'm having Ger do art for older days, just to try and add more to them. It's a slow process, since I need to focus on current updates too, but it's coming along (albeit slowly).
