Some 2.5 months ago I updated my Librelink software on my phone. The last 5 sensors have been so accurate I've been gobsmacked! Apparently this is due to the new software having an algorithm included that gives you a real time reading. The Libre readings are always within 0.04 mmol/L of my Combo pump handset when I take a BG test before meals. In fact quite often they are even closer. On Friday they were spot on... see pictures taken before dinner on Friday.

If it's of any interest the version of the software on my phone is 2.5.3.6373. I just put a new sensor on this morning. The old one is due to run out at 8.45 this evening. I do hope I haven't jinxed it with this p;ost!

That’s s good to hear @Pattidevans
these seem to vary so much for different people. A bit of a bonus and I hope that with the new algorithm it continues with future ones.
 
We'll see. I will update when I see what the new one is doing!
 
I have found Libre 2 to be more accurate than Libre 1 (but takes longer to "bed in").
Recently, I tried the Dexcom G6 trial. It was more accurate at higher numbers but I don't tend to spend much time over 10 so this is not very useful for me.
I still use xDrip to enable me to calibrate my Libre and it is lovely to do away with the MiaoMiao now.

Regarding the new Libre algorithm, I have read that it does some prediction based on the current trend to overcome the 15 minute delay. It then corrects the prediction when it get the data. as a result, you may see a reading that is then overridden - I have read of people thinking their memory is playing tricks when they see a high value and then later it has gone.

I asked about Libre 2 fairly recently and apparently our CCG have not yet authorised it’s prescription. Ridiculous when you think it is exactly the same price. Knowing how things work down here in the depths of Cornwall it could well be months before we get it.

Interesting about people seeing high numbers that then disappear. Thanks for that warning @helli . I’m now on the 6th sensor that is being extremely accurate.

Libre has always done that for me since I began using them in 2014. Not often, but I don’t think it’s a completely new thing?

It only really shows for me when there’s a steep rise/fall followed by a rapid about-turn. You can then get a scan ‘dot’ above or below the line of the graph in the reports.
 
I only got a 2 week trial of Libre2 to try and spot any patterns in my 'rollercoaster' BG levels. The alarms were great (prevented me having 5 hypo events and let me know when I needed corrective doses to prevent hyper events). I am angry that they won't fund it for type 2 diabetes even when having to take Metformin, NovoRapid, Toujeo and Dulaglutide. It really feels like they either don't care if it's type 2 or that it must be your own fault. It should be prescribed on an individual case basis or actually listen to a specialist diabetes nurse when they recommend it.
 
Yes it's a huge shame that for now at any rate, they aren't prescribing to T2s.
