I don't think lowering HIVE's powerdown time would help HIVE's price much and instead introduce unforeseen problems down the road like even larger volatility swings in HIVE's price.
SPS has a shorter power down time of 4 weeks and it's near all time lows so I'm not in the camp that thinks the power down time is to blame for HIVE's price problems.
