About damage increasement in fusion mode

I Just wanted to ask about what's stated in the "tips and details" section of this skill. It says all beam damage will be reduced to 25% and due to each beam becoming 3 and hit twice it will be 25%*6=150%, resulting in 50% more damage, but by calculating with the values of every single spectrum: 1.2 (amplification mode)* 0.45 (spectrum mode)* 0.55 (induction mode)* 6 (hits from spectrum and induction multiplicated)=0.297*6=1.782 That means that all damage increases by 78.2%, not 50%. My question about that is: Do you want (me) to correct it or leave it as it is right now?
