75:25 over 1 hour is pretty much a ‘nothing going on here’ setting for me. like if I’m sitting down to eat at 4.0 and want to make sure my slowish-but-not-really-slow meal has a decent headstart.
My more profound DWs might be more like 30-40% upfront and the rest over 3 or 4 hours. I know others who need at least some of the dose still trickling in overnight!
Now that I know you are using mySugr I can share my method for you to a) consider or b) laugh at:
In the notes of any of my problematic choices I will also make a quick shorthand note of the approach – “Pasta, DW 75:25 1hr”
Using the ‘search’ function I can then draw up a list of recent (or not-so-recent) pasta experiments, what the split was and over how long and then click into those to see what happened afterwards as a ‘logbook’ graph.
Alternatively (my earlier approach) you could just jot a note on a per-meal basis in whatever note-taking app your droid has as standard.
The key is to be able to refer back IMO, ideally with some sort of record of whether it resulted in BG nirvana, chaos or no apparent difference.
