easy question about calculating my EV

[im a model]

ive been keeping track of what has been happening once i am all-in. please calculate my expected value giving the following 6 all-ins:

i was %80 in a $96 pot.
i was %80 in a $138 pot.
i was %72 in a $56 pot.
i was %83 in a $330 pot.
i was %70 in a $108 pot.
i was %75 in a $155 pot.

i get that i should be up around $660, but i just averaged my percentages (around %75) and then multiplied that by the some of the pots (so it was like .75 times like 980). please let me know if this is correct.

You have to do them each separately. Obviously if you were 0% in a $1000 pot and 100% in a $0 pot, you didn't have $500 value.

ok. so for the data i get the that for each pot i usually win 76.8, 110.4, 40.32, 273.9, 75.6, 116.25. so i should be at 692.67. thanks sam.
