I think your thinking is correct, and it might be a little light. Remember fish grow the best when they have room to grow. If pushing the limits, I would make sure you have testing equipment to monitor ammonia/nitrite in the pond plus O2 levels when hot weather arrives. Test O2 levels before sunup when water temps are in the 80's and higher..
