Honestly, "acceptable" is in the eye of the beholder (read: owner). Especially for a daily, chasing perfection is near impossible and will drive you insane. Same goes for black cars but that's not different story! So for a daily, I consider 90% good enough. And maybe a bit less before winter since it's just going to get beat up anyway.
Your pic is good but it lacks some context. I figure percentage by the overall look on the surface. Are the scratches only seen at certain angles that no one besides you will really even notice? Are they on a really visible part of the car like the hood or driver door, or a more discreet area like the roof or rockers? Answers to those and other questions drive how I approach correction.
Personally I'd wait on any further correction until spring. When it comes time, hit them with CP and/or HCC just to see what could happen. In the end, since the average person doesn't get on all fours, twist awkwardly and try to catch just the right light to see scratches like many of us 😁, I'd say you'll be good when the car is shiny!
