I definitely understand your frustration, but the important thing is that your temps have gone up in a linear fashion overall. They are above the coverline and climbing in general. So you might just have to tell yourself not to get too hung up on post-O temps.
Sometimes I get frustrated with charting, too, but I always tell myself that the knowledge gained over time is worth it. Imagine in a few months if you have to talk to your doctor about an action plan. Having your charts will seriously aid in that discussion. So don't give up charting, even if it is frustrating.
I hope this is your BFP month. While your chart might be annoying to you, it really does still look pretty good. In fact, I think it looks better than last month's.
