Slightly higher e values don't slow the tests very much. Make them a little more attractive to the algorithm.
Still need to collect data on the change in probability with higer e values.
	E Value		Stage 2 Time
	2		10:04
	4		10:35 (+5%)
	6		11:06 (+10%)
	8		11:38 (+16%)
	10		12:07 (+20%)
	12		12:40 (+26%)
