On TR though, do you always give full dose unless they're in the 30-40s?
With TR you would shoot (eventually) anything over 50.
But if he gave you a lower than usual PS at the weekend, and you couldn't monitor, then you can skip.
With time you might mind that you would be happy to give full dose even though you are out, but you would need to leave food out for Panic, I use an Autofeeder for regular snacks while I am out, and so that I can get a full nights sleep.
When George was on insulin, I would stack the feeder with higher carb food in the early part of the cycle, to keep him safe if I was out.
On TR, with a couple of cycles where you can't monitor you might not take your dose increases to allow Panic to show you how low the new dose is getting her before the weekend. So, you wouldn't raise the dose on a friday night say, because there's a chance you could see her dose start to build by the sunday while you are out. Taking a dose increase, on a sunday night would make more sense, gives you all the way till friday night to see what her dose is doing, even having enough time to take her up again midweek.
On TR you would reassess the dose every 6 cycles, if nadirs aren't in normal range you would take the dose up, but with the limited testing, you might choose to hold a little longer so your dose increase doesn't coincide with the weekend.
And of course she earns reductions for a single drop under 50 on a human meter.
If she was looking too good on a dose, and you felt nervous about the weekend, you could take the dose down on friday morning or night to give yourself more headroom if you felt the nadirs were a bit on the low side, a temporary reduction, before going back to the normal dose on Sunday night.
With time as you gather data, and learn how she responds to her carbs at different points in the cycle, it will get easier.
Do take a look at the post I linked above, there's a lot of great info there.
