Basal Rate Peaks and Valleys

I read somewhere that within a 24 hour basal pattern, there should be one peak and one valley, meaning there can be many different rates but there should be one highest point and one lowest point overall. Have you found that to be the case with your basal rates?

I continue to fight basal need changes from hormones and am having to adjust basal rates every 2 or 3 days. My basals have increased on the order of 40% more than my initial pump settings 2 months ago. I've bumped it up slowly for fear of the day coming when I crash.

Most of the time I naturally end up with one peak and one valley but have run into a situation now that appears I may need to rethink that. I'm just wondering if others have run into this.
