The tooltip-DPS only shows the worst-case.
Which means: the Projectile damage.

For example - if you link AB with Chain, the projectile wont explode at the first 2 targets (dealing the displayed damage) but at the last target, it will explode (dealing full damage, which isnt displayed - you have to calculate it by yourself)

Fireball is working the same way btw.
