Item Repair Source 4 (Source)
I just did the clothing repair experiment again. This time I used ribbed shirts since they are easier for me to make in the factory, but I don't think this should make a huge difference. It looks like they made the chance of repair much better for non-crafters and at the same time made repair for a master crafter much worse if they are using good tools compared to before. I am not sure if this was intended or not. Anyway, it looks like we still have a bonus, but it isn't nearly as large. I have copied this from my previous results, but I am adding the new results in red.
