After some testing, i got that average time for catching fish is around ~18 seconds (min - 11 seconds, max - 25 seconds). I tested 50 catches and that was my average.
So that would give us… 18 seconds per 1 catch, BUT there’s a 1 in 12 (about 8.3%) chance to catch an item.
Math time
Chance of catching fish is 11/12 (12/12 - 1/12). Then we multiply 11/12 by 3000 and get around 3273 of pure fish catches. WHICH we later multiply by our average of 18 and get…58,914 seconds.
I had a post where I recorded a bunch of specific numbers, but it got deleted when Headless deleted the Fishing category.
Always been curious to rerun the numbers on all the different rods since pity got added, but never really found the motivation.
