Right, I see your point, when thinking about it again, I kind of agree generally.
In your case I'm completely buying the reasoning. However, Im still not convinced that a cable needs close to stipulated max amperage to get hot. From vids I've seen no excessive amounts of current are required to over time (some 30mins I think it was) would still make a SIGNIFICANT difference to OFC wire even at (what I remember as: ) rather real-life experienced amperage.
This is perhaps a bigger problem in my eyes than in yours, since our market over here has flooded with low cost low quality CCA wire the last couple of years, even if prices is not more than about 30% less expensive than OFC still.
Some people are making a good deal out of low quality. Not enought people discuss material, but stick with what gauge the cable is.
Keep the good work up!
Cheers,
