Realistically, you should have increased to 1.0u -- not a skinny dose. I would just start shooting a full 1.0u.
I also want to strongly encourage you to get a before bed test every, single night. Many cats visit lower numbers during the PM cycle. In addition, without PM testing, you are missing half of your data. The more data you collect, the better. you will understand Yoshi's patterns. Without data, everyone is guessing and it's very hard to provide you with any reliable input.
