It is a very valid question, though. I think I mentioned when we met that Devilet, apart from bug fixes and occasional extra features, optimises the power supply algorithm in firmware updates. Since the power supply is different in the D-Premier, the Expert and the Pro, the optimisation is probably tailored for the latest hardware, in this case, the Pro. I'm wondering if it might actually make earlier hardware versions 'less optimal' than before.
