Thanks all three of you for your explanations. I have just one last question. As I understand the brakes on the 8xxs have the variable continuous brake (similar to 395s?) unlike the 387s but do they have the power notches like the 387s or is that variable too? Sorry for the rather specific questions but I am going to be using the MML a bit more and these units will become nearly as common to me as the Azumas and I do find that trains with the power notches can be less smooth on acceleration than those without. Thanks, and again sorry for all the questions!
Variable. There is no"Notch" system like you have on older traction, same goes for power. There are labels / little markers though which were meant to replicate notches of power and braking steps as a reference but the controller itself had no resistance or feel at these points.

On 8XXs the brakes do perform differently. A 5 car brakes differently from a 9 or a 10 and a minimum brake on one might give a 20% brake but the next set might give you 15%.
In addition a braking control unit adjusts braking performance to coincide with the drivers demand dynamically, so if the set is full and standing it'll compensate for this to a degree. In theory anyway.
You get a varying experience compared to traditional air brakes but they are also very rapid to modulate as a result.
