I don't understand cache fully, but I do know that if you open Dev Tools in Chrome and long-press the Refresh button, it will give you a drop down with the option "Empty Cache and Hard Reload", and also shows you that Shift+Cmd+R is just Hard Reload without emptying the cache. Sometimes I need to do this, but I don't fully know why or when.
