Lightning Strike question

I am wanting to make a LS templar but am not really sure about the damage calculation
Does LS damage calculation go like this?
Physical damage = 100
Melee LS = 50 physical + 50 lightning
Projectile LS = 35 physical + 35 lightning
LMP LS = 5 projectiles
Total hit in melee range = 50 + 50 + [(35 + 35) x 5] = 450
Total ranged hit = [(35 + 35) x amount of projectiles hit] = 70(amount of projectiles hit)
Can someone please enlighten me on this? Thank you!

Anyone? I just want to know whether or not at melee range, the monster will get hit by 1 melee + 5 projectile or 1 melee + 1 projectile
