Libre Arrows!

@Rachox what does the graph look like?
I don’t pay much attention to the arrows as they don’t include many points.
The graph gives a better idea of trends.

horizontal! Why

I think that horizontal arrows indicate that the glucose readings are changing slowly. To me that is good.

When I wear one mine are always horizontal unless I've eaten something very carby. I've got used to ignoring them and looking at the graphs instead

Because it only shows the arrow when your BG is changing quickly, not slowly. Which hardly ever happens considering you're a very well controlled T2 and not the T1 jumping from the 2's to the high teens for who this device originally was intended.

I wager at some point between 19:19 and 20:20 the arrow has pointed down, but you weren't looking at that time. By 20:20, when you scanned, it must have been rather stable.

I never look at the arrows, for me, they're utterly useless, being rather stable. Instead, I scan, which shows the current number and the graph for the past 8 hours, and then press the little arrow at the top left to make it show the last 24 hours, making the rises and falls more pronounced.
On that graph I can easily see if I'm rising or dropping, and much clearer than with those arrows.
Take my current graph for instance (and keep in mind it reads lower than blood for me).

Had something to eat at 3:30 and took a little less insulin than it turned out I needed because I'd been lower than anticipated all day.
Had two carb heavy beers starting at 5:30, dosed normally for them, rose up to over 7 with a fingerprick, shown as 6 on the graph.
Figured I should have added a correction for the food before and took a small correction at around 7.
Which wasn't needed after all, judging from the steep drop, I had just been impatient.
Dropped me back to close to hypo when I was about to eat, a low carb meal I usually need a couple of units for, but didn't take them considering I was on the low side already.

To bring me to my point:
Right now, I can clearly see I'm rising from the food in my graph, even though the arrow stays horizontal because it's a slow rise.
The graph is much more informative than looking at the logged scan moments, that log is the one feature of Librelink I never use, except to get me to the 24 hour graphs with notes when tapping the page.

It’s a bit up and down but in target range!

But now I'm curious as what you did at around 8:30 am. Got out of bed or had breakfast?
I'm guessing the slow rise after 5 was either DP while you were still sleeping, or the point where you got out of bed.
The carb killa bar I guess is the little peak after 11 pm.
The friendly bump after 1:30 pm looks like it was the 'food dr ar'. Some kind of bar?
Your evening meal had no impact whatsoever.

But what were you doing between 3:30 and 4:30?

Remind me to not wear my sensor if I ever plan to commit a crime, the stress is sure to do some very unusual things to my BG, and it would be way too easy to find the effect and thus circumstantial evidence in my readings!

Breakfast: my usual low carb coconut ‘porridge’ with strawberries washed down with a black coffee.
Late morning: black coffee and a carb killa bar.
Skipped lunch.
Mid afternoon: black coffee and a food dr ar
Dinner: crispy cheese omelette filled with baby tomatoes, mushrooms and more cheese followed by SF strawberry jelly and cream.

Horizontal arrow just means your figures are changing by less than 0.06 mmol/l per minute, but even if you are only changing by 0.05 per minute, if it keeps doing that, then after an hour your figures will have changed by 3 mmol/l.

Ha ha I love your analysis,

So much to see in those graphs, even if I didn't guess right!
Still, the drop between 3:30 and 4:30 is remarkable, it's the kind of drop I see after half an hour of swimming.

My insulin resistance is much less in the evenings it would seem!

Same!

I am now in a position to be able to self find the Libre. I am on my second sensor and have noticed that the arrow is always horizontal regardless of the reading! An hour after dinner this evening it read 3.4 which I suspect is a compression low as the back of my arm was resting against a cushion. However even with that low reading the arrow has stayed stubbornly horizontal! Why?

There’s nothing wrong with a flat arrow. It just means that your blood glucose is currently stable at that level, whatever that level is. So just think of the arrows as saying “it’s rising….it’s dropping…..it’s stable”.
