Velocity software has extensive handson experience in building and deploying cuttingedge mobile applications and games. This is an old question but still, something you can do is borrow velocity from agile software development, where you assign a weight to each task and then you calculate how much weight you solve in each sprint or iteration or whatever dlc you use.
There is no scientific evidence that measuring velocity improves planning effectiveness or team performance. Despite being way better than the lines of code, it is still tricky and only works with.
