Hi Paulina! Been awhile since you posted good to see you start a new thread with a new Subject line. The link to your previous post is perfect too.
All that being said, Yes, I think you could go back up to 2, but there were also times when you should have reduced the dose. On 5/9/21 he dropped below 2.8 so he "earned" a reduction from 2.75 to 2.5 (which you took so that's good) but then over the next several cycles, he dropped below 2.8 again and you should have reduced to 2.25 on 7/9/21
On 12/9 and 19/9 he also dropped below 2.8 so should have earned reductions on those days but none were taken until he dropped again on 25/9
Then, you reduced the dose 3 times (from 2.25 to 1.75) when he really didn't earn them!
The way this whole thing works is when they drop below 2.8, they "earn" a reduction and you should almost always reduce by .25 at the next shot and hold that lower dose for at least 6 cycles or more to see how they do on the new, lower dose.
Also, when you reduce depends on the dosing method you decide on. Most new members use the Start Low, Go Slow method which means you'd reduce when he drops below 5! On the more aggressive Modified Prozinc Method (which you test enough to do if you want), reductions are earned when they drop below 2.8.
You should read through the
ProZinc Dosing Methods and decide which one you want to use and put it into your "Signature". If you choose MPM and it's not for you, you can always go back to SLGS and vise versa so you're not "locked in".
There's a lot of nuance in diabetes treatment and it takes experience in reading spreadsheets to know when to reduce, when to hold and when to increase. If you'll try posting daily, it'll really help.
You don't necessarily have to say much. Just something like "Frodo seems to be doing OK today but checking in in case I'm missing something" is more than enough
