Dynamically adapting would be by design never too early/late.

I already tried to address this in my original mail. If I had those 4 coins, I would use a denominator of 987 and discard the difference as fees. ------------------------------------------------------------------------------ EMC VNX: the world's simplest storage, starting under $10K The only unified storage solution that offers unified management Up to 160% more powerful than alternatives and 25% more efficient.
