Great summary. I look forward to seeing how your testing has progressed and how your project has responded to the actual testing. It was hard at the review to assess the project with a plan to test - it is essential to your success to get that feedback and fold it into your process. You cannot wait until the prototype is "ready" -- you will be too invested in the result of your prototyping and it will be hard to accept the changes that will have to happen. Go ahead an test the attributes of your product that are based on assumptions that need to be proven (eg that certain behaviors will be the result of wearing a form on the wrist, or touching a certain material - or that the wrist is the right place for this product!).
The boards were looking good at midreview.
