We just published a new post that provides some of the foundation required to understand the implications of our recent VP Management design changes. It hopefully answers your first question (your account can have up to 1/3 of its pending balance delivered on any post).

To answer your second question, there is no need to consolidate the voting accounts. While it would help with the randomness, that's a temporary problem. Consolidation would result in more permanent problems down the road, if HIVE prices ever recover.

We will go deeper into the implications of VP management in our next updates, and share our attempt to guess when things will normalize.
