I have intentionally avoided using the number of images as the measure of content in an update. Firstly, because the images often take different time to render depending on the content (e.g. when a lot of characters or costly effects are used), and secondly, because the work done apart from the rendering (e.g. creating the scene that can then be reused over several images) can have a big impact.If the update contains 250 - 300 images again, will you write here that you were wrong? Or does it have to be at least 600 images.
Let the facepalms come to me.
The fact is and remains that development performance should be measured not only in terms of time, but also in terms of the work put into it. As I said, the probability is high that this update is not faster than usual, but simply has less content.
