It usually is never how we presume it to be.
My take: If we win the first suit, all the others will likely fall, therefore the first win will be the HUGE spike and then down a little to a plateau. There will not IMO be a roller coaster after the first win, just continual spikes, plateau's, then spikes again with each win. JMHO. Using the logic of my first statement, I could be just as right or wrong as you! LOL ;) GLTU
