Because we are starting on a new Wiki, imported from the old, sometimes there are bugs, broken links, things that doesnt go right,there is no official thread to that, so feel free to post it here
I will check personally every page and link if I can, but if you want to help, you are welcome.
There seems to be a thread link that was missing from the last wiki that was copied over. It might be best to remove it or find the thread in question and link the spreadsheet and calculator from there.
HiddenAnon you can find the spreadsheet here, the calculator here
Fulminato I added links to those threads on the page, now it will be easier for people to find them.
