    just to be sure, if you are comparing only 2 different groups (like 2H, and 2CL) then you would use Cis tand trans but if it is more than 2 groups you would do Z,E (like 2Cl,f,and H)?

    yup that is correct. More than 2 groups is E/Z and 2 or below is cis/trans

    how i look at it is that, if the carbons that participate in the bond in question BOTH have an Hydrogen then we use cis and trans, if not use E and Z (for a polysubstituded double bond)

    can someone validate this so i can sleep better at night? its kinda a rule i came up with just by noticing the patterns instead of using the traditional meaning.
