EEVBlog #543 - PCB VIA Current Investigation

Dave tests the myth that plugging a PCB VIA with solder does nothing (or not much) to improve the current handling capability. Is manual wire feed-through any better? Does the industry rule of thumb of per VIA have any basis? What is the typical plated VIA/hole thickness?
