The thing i like most about this presentation method is it really likens the phrase lesson to a high lavel routine. It’s pretty general knowlege that high level students need routines that fit their individual needs and this is a great way to incorporate a routine lesson style as well. After going through the phrase cards, completing the story you created for the student, and letting them come up with their own phrases, have you ever tried applying L&R routine questions to the story? Granted this works best if the student has a background in using pre-intermediate and intermediate level routines, but a high level student should be able to ask you relevant questions about the story even without lists of questions pre-taught. For example, if your story is about “childhood” simply have the student ask you questions about your childhood and respond with the content from the story, pausing periodically to let them ask another subject appropriate question to keep the conversation moving. I like all my high level students to be comfortable in the drivers seat of a conversation.
