Nicely done, but I don’t understand why you are saying N+3 as the Massive Developing Chart lists a time of 7.25 min in HC110 dil. B for the film at ISO 800, which what it seems that you used. Certainly pushed one stop, but it doesn’t seem like N+3 which should be a lot longer (14-15 minutes??).
Oops! It should say “N+1”. The time is accurate, however. Well caught, Ken! 🙏
