You may be surprised how quickly you can recreate what you last remembered, because you knew exactly what you typed/edited to get to that point. Often, it can even be a good thing, and you find a better way to state or do something, that is more efficient on concise, too! This has happen to be with many essays in the past!When rewriting it, I immediately figure out better ways of organizing ideas and sentences, and same goes for CAD stuff. Oftentimes, it is even faster to redo all that work than to tediusly search the computer for hours looking for the settings, recovery tools, temporary autosave files, etc.
