huum, ok so it was nice to have this information, but ok.

There might be an in-game cap to the value of durability. If I understood your question right. Honestly I put this up so long ago, I don't even remember what values I used.

the factor of support of the tools, greater or less than the time they are found in the inhabitants? or is it the smallest longer duravel? not clear configuration values, I used 1000 and did not notice any difference
