In 4U the displayed raw for weapons was divided by a weapon multiplier before calculating damage, the multiplier for GS is 4.8, so a weapon with 1248(to keep things even) Atk would have 260 true raw. The displayed Element and Status effects of weapons have a multiplier of 10, thus to find the true value you had to divide by 10; this is also why if you had 200 Poison and Status Atk +2(1.225 multiplier) it would display 240 instead of 245, because the 5 would be a decimal in actual calculation and thus would be dropped.

The only difference in X/Gen is that you don't have to divide by a multiplier to reach the true Raw/Element/Status values. Damage Calculation is still the same for the most part, with changes to MV's being the only real difference.
