Same number of LingQs everyday

No matter what day of the week it is, I always seem to have the same number of LingQs (25). I always add, change the status of certain words and I always happen to wind up with 25. Is this just a coincidence or is the maximum number of daily LingQs 25?

You can change this number in your settings.

Thanks! I knew there were days I had more than 25 to review.
