That's a Good Surprise!
It’s always inspiring to find out that you are farther along than you think.
This is often the case for me. However, part of it is psychological. Today, after a good stretch and a hang, I thought that my unit looked small. I was quite gloomy about it. I measured a flaccid stretch and, guess what, it was a quarter inch longer than ever. I attributed this visual anomoly to a slight increase in flaccid girth which made it look shorter.
The point of this diatribe is that your measurements will almost certainly fluctuate a little. So, if you measure again and it is a little shorter, don’t freak out. It’s likely that the next time you measure it will be a little longer.
