There are a couple of factors which may be influencing Podo's numbers.
First and foremost, Lantus, when a cat (or human) is better regulated, doesn't have a "curve." Rather, the curve is flat. It's why when we encourage people once data ready, to shoot low to stay low.
There may be some irregularity to Podo's numbers due to the shifting in shot times. The closer you are able to keep to a 12-hour schedule, the better the response will be. If it's a fact of life that this isn't possible, just take the issue into account.
