Nice video GB - only thing I do differently is that I do not put the inner cover between the bees (deep hive body) and the feeder. Maybe you have it right but I haven't used the inner cover at all while feeding - Just bottom board, deep hive body, feeder and outer cover. Once you remove the feeder then put the inner cover between the bees and the outer cover.
Just a thought - other than that you look you have things headed in the right direction. Welcome to beekeeping!
