Very disappointed – Dictation Pro - Talk to text Review

Testing it at the office by practicing a couple minutes of my seminar presentation with my iPhone 7 in my shirt pocket to see if it would pick up the sound through my shirt, I felt good that I would get my 1.5 hour presentation captured in the Pro version I had just bought. Just before starting my speech, I put my phone on airplane mode stuck it in my shirt pocket and began my talk. When I looked at the app after my speech I only had about 5 minutes of it. What happened? What is the capacity of this app? How many minutes will it transcribe?
