I made a spreadsheet from the calculations of each page which will estimate the XP/hour and also time to the outfit given different Fishing/Hunting levels. This was inspired by the experement in the creatures subsection at the time of writing this. Hope this helps someone (and also hope my numbers are correct).
From the data if your value of X is just higher than what you need to catch a new fish you'll catch it very rarely, so your XP/hour won't necessarily bump up significantly if you only have a small chance of getting the new fish. RansomTime 18:48, 9 November 2019 (UTC)
