Proper Sequence for Lindamood-Bell Programs?

Hello! My friend is an adult recently diagnosed with Developmental Dyslexia. I know, what took so long, eh? His neurologist recommended Lindamood-Bell. He willingly submitted to the testing at our local LMB center. My question: I'd like to know if there is a preferred sequence for the Lindamood-Bell programs. He's specifically interested in Seeing Stars and Visualizing and Verbalizing. He's going to commit 4 hours a day 5 days a week for up to 12 weeks. Our local LMB center suggests the two programs, but we'd like to have an outside opinion without sales pressure about doing the two programs at the same time or if one should go first and then the other. What say you all? Thanks!
