Chart Help Please! I'm a bit confused

Here's my chart. I have a few questions from people who are seasoned charters. I am hopeful because my temps are the high test they've been in 3 cycles of temping. But I'm 8dpo and thought I would've seen a possible implantation dip by now. Do you think so? Also I usually have a bit of Rocky Mountain temps but my temps have been so consistent it's scary lol and they are right I have two thermometers - is that ok? ​
