Congratulations for the switch, looks like Susie will do very well on Lantus since she is already flattened
If i can ask, is there a specific reason why you can't test during the night? It is a lot of effort, don't get me wrong but during the night they tend to go lower and it is safer to have an upper hand on that. I saw from your spreadsheet that you are aware of this and lowering the dose for the night which is not very good for the way Lantus works, it needs consistency to show best results. On the bright side you "only" need to follow the active cycles so if you take a +2 you should know if it is worth following or not.
We started shooting schedule with Chico at 9AM and 9PM but during the first active night cycles we realized that it takes us up until 3-4AM to pass nadir so we quickly changed his shooting schedule (with half an hour per day increments) to 7AM and 7PM haha Now most active nights finish at 1AM which is still acceptable.
Thank you Summer for your kind words

we wish you and Susie lots of patience and luck as well
