I used to do it a lot more than I do it now and actually, I don't get that way for an entire tank anymore, but maybe just a single drive. Generally, once I have a bad moment, I spend the rest of the tank trying to make up for it, which ultimately leads to a tank that's still pretty good.
No tank will ever be perfect, but one horrendous tank can mess up your 90 day average pretty bad for a while. Keep your eye on the long game, but accept you're human, male and you have an ego to keep happy once in a while
