I thought it might be helpful to post images of a “typical” day on Fiasp vs. a “typical” day on Humalog. As you all know, there really isn’t any such thing as a “typical” day as it seems that every day is different so maybe “representative” would be a better term to use. In any case, I think you will get the gist of how Fiasp is working for me vs. Humalog. I’m posting 2 screen captures for each… The daily CGM curve from my Tandem t:slim X2 pump which also shows the pump calibrations. The “gap” on the Fiasp one is where I had to do my weekly CGM sensor change.
Here are the Humalog screen shots from Glooko Diasend reporting application:

You can see from my basil rates for both Humalog and Fiasp, that I have a multi-tier basil program and have developed that changing rate over time based on my body’s need for basil insulin at various times of the day. I did have to tweak it for the Fiasp and that is why the blue line looks different on the two.
One thing to also note when viewing these is that I don’t eat breakfast. I found that breakfast would start me on a YoYo where I was chasing the ups and downs for the entire day. Now that I’m on Fiasp with significantly reduced post meal peaks, I may try to going back to eating breakfast. I’ve been on the “no breakfast” routine for several years now and I have the basil pretty well tuned so that things stay pretty flat until I do lunch… Usually between 11:00 and 11:30.
You will also notice one “oops” at the end of the day on the Fiasp day. I had a snack and over estimated the carbs and that drove me a bit low.
You will also notice that I was “chasing the high” on the Humalog day and had to do multiple correction boluses after dinner. I also did my boluses well in advance of eating lunch and dinner and still had the significant peaks with the Humalog.
As I have stated, Fiasp has been truly a game changer for me. It may be that my body physiology is just a good match for how Fiasp works and I may be the Fiasp poster child so your mileage may vary
