There may be a way to simplify, but it may depend on the nature of your calculations to get each step.
Instead of calculating the count for step, could you instead make one Dimension Calculation to the effect of:
IF such_and_such_criterion_is_met THEN "New Lead"
ELSEIF such_and_such_criterion_is_met THEN "Lead Contact"
Then put that on the Row shelf and SUM(Number of Records) on the Column shelf.
Then you can right-click on SUM(Number of Records) and add a quick table calc
percent difference from previous.
