Yeah man I know exactly what yore talking about! Often when I listen to myself talking in for example one of my video game live streams or some other recording, I often get surprised and cringe over how much I actually stuttered compared to how much I felt I did in the situation. However counterintuitive it may seem, though, I guess it's actually a good thing! It would be worse for ourselves if we thought we stuttered much more than we actually did, because, as I'm sure every stutterer knows deep down, other people don't care anywhere near as much as we do. So this... phenomenon is actually a step in the right direction - a step towards being less worried about our stutter :) This just reminded me of an exam I had in the summer of 2013, it was a group exam, so there were two teachers and then 7 of us (very large group), so naturally I felt even more pressured about stuttering less so I wouldn't waste the others' designated speaking time etc... I felt it went okay, it could have gone worse but definitely also much better. A few days after the exam, however, my best friend, who was in the group, told me how he noticed that I almost didn't stutter at all during the exam, he said that he actually thought "wow" during the exam. We usually don't talk much about my stutter, and he brought it up randomly, so I know he really must've meant it. I guess that's an example of the opposite of what you're describing OP, and obviously I was glad that my stutter hadnt been as bad as I thought, but it was almost worse that I'd worried so much about it!
