Well there not really seconds, just depending on the core and the placement of it the cg can be not inline, the general rule is the mb is found by making a line 6 adn 3/4 inches through the pin and cg, the end of that line is the cg but many balls these day are just ones that have the cg out of line and sas two headed boy mentioned it can be an advantage, its the same way on my trifecta!
