Winning is great and losing sucks but within that archetype exists degrees of each model. There are great wins and there are bad losses and the feelings about those outcomes differ greatly, yet in direct proportion with their moderate counterparts and with each other. A great win is so much more exhilarating than a regular win and conversely a bad loss is much worse than a regular loss but the correlation of the extremes is equal; a bad loss hurts as much as a great win uplifts.
A bad loss can be defined as a game you should have won, we’re winning at one point and typically occurs against a meaningful opponent and maybe in a relevant situation.
