Does my chart at least look okay?

After my last post, and someone being completely rude, I went through my thermometer again, and triple checked my temperatures and I see now they are all taken between 618 am and 635 am. Is that too large of a time difference to be accurate? Does my chart look okay, this is my first month charting. Please only kind answers I am just looking for advice. My chart from Kindara looks a lot nicer and IDK why.

Thank you
