I want know it too! I get the milk from raid it give a boost as 80%pain +20%breath and +20%immunity. But I don't know how long does it last.

by reading xml file it seems to be just above 2 days (<severityPerDay>-0.45</severityPerDay>)

For the wool, here：
:\SteamLibrary\steamapps\workshop\content\294100\859466666\1.4\Defs\ThingDefs_Items

<StuffPower_Armor_Sharp>0.32</StuffPower_Armor_Sharp>
<StuffPower_Armor_Blunt>0.32</StuffPower_Armor_Blunt>
<StuffPower_Armor_Heat>0.32</StuffPower_Armor_Heat>
<StuffPower_Insulation_Cold>32</StuffPower_Insulation_Cold>
<StuffPower_Insulation_Heat>32</StuffPower_Insulation_Heat>

so all numbers are just 32! That some lazy ass work!

Seriously, edit them yourself. As a comparison, hyperweave has a Armor_Sharp of 2.00, Armor_Blunt 0.54, and Armor_Heat 2.88

So, that's actually the lowest sharp protection in the game, inferior to even cotton and the common wools. When Thrumbo*fur* is the highest sharp protection in the game at a 2.08.
Against blunt weapons a 0.32 pretty good actually, only inferior to devilstrand, thrumbofur, and hyperweave, but almost nothing you make out of textiles has a blunt protection multiplier high enough for it to matter.
For heat armor, a 0.32 does outperform cotton cloth, but it's vastly inferior to even patchleather, and less than a third of the value of common wool.

As far as insulation goes however, this is excellent. 32 degrees of cold insulation would be fourth best in the game, beat only by megasloth wool, thrumbofur, and guinea pig leather.
And 32 degrees of heat insulation is better than *anything* in the vanilla game, beating even devilstrand and hyperweave by a large margin.

Overall it seems like the modmaker either didn't know how textile stats worked or just didn't care at all about balance, with the end result being that an extension about Thrumbo ranching doesn't deliver any of the things people want from Thrumbos.

You're probably better off with a simpler mod that doesn't add new items to the game and instead just makes the shearing process produce vanilla thrumbofur, like Thrumbo Husbandry by HoboOfSerenity. Though that won't fix it being classified as a form of leather rather than fabric, so you won't be able to make tribal headdresses or broadwraps or face masks or tuques...

Looks a lot different to me. I presume it's because of an update, or maybe I have another mod that changed it without me knowing (unlikely), but here are my stats;

<statBases>
<MarketValue>20</MarketValue>
<Flammability>0.2</Flammability>
<DeteriorationRate>1</DeteriorationRate>
<StuffPower_Armor_Sharp>1.92</StuffPower_Armor_Sharp>

<StuffPower_Insulation_Cold>30</StuffPower_Insulation_Cold>
<StuffPower_Insulation_Heat>42</StuffPower_Insulation_Heat>
</statBases>

<Beauty>8</Beauty>
<WorkToBuild>1.2</WorkToBuild>
<WorkToMake>1.2</WorkToMake>
</statFactors>
</stuffProps>

I don't know about you guys... but I think that's rather overkill

It's way better than Thrumbofur in almost every way, with the only exceptions being:
Sharp Damage (2.08)
Cold Insulation (34)
Work to Make/Build (1)

It's also way too defensive for wool. For reference, all wool types have 0 Blunt Armor, 1.1 Heat Armor, and the most protective wool, Megasloth Wool, only has 0.8 Sharp Armor

Good on the mod author for taking effort on making this thing useful... but I think that was a tad bit too much
