Glad you are getting to grips with it. There is a lot of learning involved but the lower numbers are a reward when you get it right.
Your figures are looking much better, keep working at it.
I take my basal (background one) in the evening and I find it depends what time I take it has a bit of an effect as to how low I am next morning. If I take it about 11pm the figures don't go down much at all usually but if I take it early, say about 9pm, it can get quite low in the morning, so maybe experiment a bit with timings if you want to get a bit lower at certain times of the day.
