I'm not so sure. They are comparing end of year to end of year. Each year you will have some who do re-up. Yes, there are different ways of slicing it, but if you compare current as of today to end of year last year, that is pretty close to apples to apples. That doesn't misrepresent anything.
To get what you want, you would want to compare post recharter to post recharter. Say, April 1st to April 1st. Again, you wouldn't compare Oct to April 1st of this year. It wouldn't be apples to apples.
