Confused about ovulation tests??

Hi everyone :) I am completely new to this TTC world and I have just recently started testing. I'm currently using the easy@home tests twice a day and registering it in the Premom app. However, I know it's still very early in my cycle, but l'm confused about this huge T/C ratio decrease with basically 2 hours difference. Is this normal?

Thank you in advance for all your help and please forgive me if this is a stupid question, this is a new world to me.

p.s. I do feel like l'm over testing today, there is clearly no need to test with such a small time difference. Normally I test in the morning and in the evening but today I was curious about the TC ratio along the day :)
