I got 2 stras for the mission time of missions 1 and 3. Then I wathched a 3-star walkthrough on YouTube and I have a strong feeling that it wasn't really faster than mine. I can't prove it, since the game won't show your time stats and I wasn't playing with an external timer. The walkthrough has a couple of places where some time might be won (not much though), but otherwise looks even more relaxed than mine. But I was using save/load a lot.

So I wonder: does the mission time counted as an in-game time, or not? Like:
* Is there any penalty for quick loading? Or is it rewinds the timer at all?
* Could it be processor dependent? So that real-time deadlines are more strict on faster CPUs?
