Tex's Lucky Spinner Event Calculation

I have logged in every day, see checked daily rewards.  I have completed both weeks’ tasks.  I only have spun 59 times which completed all my spins earned. I know people are upset about not being able to complete the challenge without buying spins, and I fully agree.  On the forum, 66 is the max attainable number of spins without buying, why dont I have 65, one spin is remaining for tomorrow’s check in.
