Some of this is in your control and some of it isn’t. Dont take the data personally. You aren’t experiencing anything bad from the data, are you? Your just playing more of a game with numbers. ??? If you scroll out from the data, I bet it looks more flatline, if that makes you feel better. Everything is relative. Scale changes things.
Paintball is hard to predict. If you are running uphill under high adrenaline, I would guess it raises your BG, until you burn up all the glycogen, then it is more likely to drop rapidly. It will depend on your body. Also, temperature can make a big difference. Were you playing outdoors in the winter?
I’m a back country skier and for some reason, when I’m really enjoying myself, it runs high. But, there can be huge oscillations, and rapid ones, over a six hour period. My numbers might run any of the following. Depends on the mountain. Depends on the year. But, in general I’ll tend to run low, like in the 3rd pic, if its just typical, groomed big mountain skiing. But, if there is terrain, and I’m jumping around and really working (like in the back country), and enjoying myself, its more likely to be the first two pictures. But, you might be different.
That stuff is the most difficult stuff I do as a diabetic. Sometimes things get weird. I like to know the ski patrol on duty and ski at a small, challenging mountain, were everyone knows me and my malfunction.
