first time bard CoD question

[supermonk]

bard is probably one of the few classes i've yet to play and let me tell you it's really fun. i'm trying to learn how to quad kite and have a few questions with song mechanics.

currently i'm doing: selos/stop, CoD/stop, CoD/stop. what i want to know is: is CoD more similar to a dd spell rather than a dot? like, does damage land right as the spell finishes? am i doing double the damage by stopping CoD and recasting CoD vs. lets say selos/stop, CoD/stop, regen/stop?

thanks in advance.
