I did ready your post fully, but it seems you did not read my comment fully.
Either way you do it, it is bad for governance.

The only reasonable thing is:

• The same powerdown time for all operations (To avoid splitting up stake).
• Long powerdown time to stop exchanges from powering up to manipulate.

Like some people below pointed out already. Why should we hunt for those few thousand investors to invest in hive but have a shitton of competition but instead we hut for app creators and consumers to buy hive for RC etc.
