Expected Behavior

From the config:

#Settings for the salvager
[salvager]

	[salvager.partLossRate]
		#Minimum rate of part loss when salvaging items. 0 = no loss, 1 = complete loss.
		#Rate depends on remaining durability.
		#Range: 0.0 ~ 1.0
		min = 0.5
		#Maximum rate of part loss when salvaging items. 0 = no loss, 1 = complete loss.
		#Rate depends on remaining durability.
		#Range: 0.0 ~ 1.0
		max = 1.0

The way I understand it, with full durability I will get half of the items back. With almost no durability, I will get nothing back. In reality, the behavior seems to be mostly random. Example, courtesy of @gogedo:

Shovel = 1 Stick
Sword = 2 ingot
Boots = 2 ingot
Helmet = 1 ingot
Pickaxe = 1 ingot
Leggings = 5 ingot
Chestplate= 2 ingot

@ViRb3 Are those outputs for vanilla items exclusively? I was using SGear items when I tested this.

@SilentChaos512 Vanilla items exclusively, yes.

Yes, it is deliberately random.

Loss rate for a given item being salvaged:

• If ratio is how damaged the item is (0.0 to ~1.0)
• Loss rate is (ratio * max) + ((1 - ratio) * min)

If you turn on debug logging for Silent Gear you can see the calculated loss rate when you try to salvage something. As expected, loss rate with min = 0.5 and max = 1.0 is going to be 0.5 when salving a fully undamaged item.

The loss rate is applied against each ingredient. So yes, if you throw in a 100% durability iron helmet with min = 0.5 and max = 1.0 as in your example, here are your possibilities:

• 3.125%: 5 ingots
• 15.625%: 4 ingots
• 31.25%: 3 ingots
• 31.25%: 2 ingots
• 15.625%: 1 ingot
• 3.125%: 0 ingots

The mean yield of one fully repaired iron helmet would be 2.5 ingots, i.e., throwing in 100 of these iron helmets should get you around 250 ingots. There is a distribution here, so yes, throwing in just a few items could very well give you a number that seems very "high" or a number that seems very "low".

Not sure I see any sort of bug here.

Yes, it does seem like everything is working as intended. Each item that could possibly be returned has the loss chance rolled against it. So salvaging the same thing will yield different results.
