More inertia has the benifit of helping to keep the key in motion so the finger doesnt have to, but at the same time tends to be more of a problem when the key wants to change directions. The points about changing key speed during the keystroke made seem to me to be less relevant, but perhaps you might have some insights about that you could share with us. Much has been made of the idea that more mass requires more effort to move, yet at the same time it is ignored that once that mass is moving it takes less effort to keep it moving. In reality these are flip sides of the same coin and to some degree whats good about the one side is bad about the other. And thats just inertia. I suppose we have to assume there are similar tradeoffs in just about every aspect of this "how much lead and where to put it" question. And in the end this is all connected to the question of how much hammer mass do we want to impact the string, and why.. Personally, I like a good deal of mass in the keys because I like how that feels in an action, and I like how much hammer weight I can counter balance with it. I tend to place my weights centered a bit closer to the balance pin then Stanwood does, as I like the feel of this kind of configuration. On the other hand, it seems to me that one of the jobs piano techs have in this connexion is to identify what the pianist in question wants and attempt to provide that for her. In answer to your querry, it is my guess that the reasoning for the acellerated action has more to do with key motion after the finger gets it moving, and after it rebounds of the keyfront cushion, as this is where more inertia is more an aid then a hinder.
