+ being too fast on accident. This estimates and adjusts for recent
+ hashrate aggressively (lots of random error) but corrects the error by
+ CST adjusting the difficulty during the block.
+ It checks to see if there was an "active trigger" still in play which
+ occurs when recent block emission rate has been too fast. Triggers
+ are supposed to be active if emission rate has not slowed up enough
+ to get back on track. It checks the longest range first because it's
