Chapter Memorization Question

Do chapter verses have to be memorized together? I have been doing Romans 12 for months now it seems (I'm not sure on the total length of time really), but I've been working on it for so long that I can actually recite the entire chapter even though much of the chapter is still showing as learning. My other verses have been coming in at a decent pace, but my Romans 12 verses seem to be in limbo. I mark them as 5's with every chapter test and daily memorization when they pop up.

Am I missing something possibly?

Just as a follow up, I wanted to make sure I understand.

My interval numbers are low, but I have a huge number of attempts on these verses.

Romans 12:3 Attempts: 54, Interval: 20
Romans 12:4 Attempts: 53, Interval: 14
Romans 12:5 Attempts: 52, Interval: 17
Romans 12:6 Attempts: 50, Interval: 20
Romans 12:7 Attempts: 50, Interval: 22
Romans 12:8 Attempts: 49, Interval: 17
Romans 12:9 Attempts: 49, Interval: 18
Romans 12:10 Attempts: 50, Interval: 14

You get the idea. Am I missing something in the formula? I have attempted these verses so much I can actually recite them, but yet they still fall back as if I have months of work left on them. Any thoughts?

Maybe the best thing to do would be to ask on the Feedback tab…the little black box on the right side of the screen….

And why you have different intervals is because you rated them differently.
