Looks like it is kicking in after the small initial rise. Nice to see another blue number. That is about the most action you want, going from 273 to 195 in an hour is getting close to the most you would like to see them drop. Too fast of a drop can cause a bounce. I don't think that warrants any steering yet, but if she continues to drop like that it might be good to slow the drop down. Sandy would be better able to answer that question.
On a house cleaning note, the SS gave me a little scare, I have always done:
22
0.25R
You have the R after the 22u of lantus, not a biggie but did perk me up for a sec, even though I knew you were only shooting .25R. Don't forget to update the SS, makes seeing the pattern a bit easier
