Advanced tools have either been using their parent basic tools' custom_materials or their custom_materials were lowered for what I presume was destructive experimentor work. This counts for recycling these items in an autolathe as well. In the first case, alien tools were made out of the same material amount as their basic counterparts, and in the second case - the recycling results were heavily lowered.
Also kills off some single-letter vars since I'm here.
