I get you man, and I appreciate your comments, all it can do is help others in the future!Nah man, don't edit anything, "click-bait" totally a joke boss. just adding more data points here, not discounting anything.
Temp guns need to be more commonly the first step, anyone can do it! I only added additional comments for future readers, not to critique the post.
The temperature method is awesome and works often - but it doesn't have 100% efficacy. Getting technical with friction/heat is fun to me and I would bore the !()(%*!% out of almost anyone traveling that rabbit hole because I like data and statistics and rates and mechanical systems to a fault. But it's more complicated than that, since some don't show overheating, and future readers who might not be mechanically inclined would probably be better off knowing that to avoid a possible false negative.
