You don't get any more points for doing the jumps in combination than you do performing them singly or in a sequence like Sasha Cohen likes to do in her long programs.
The first part is misleading: comparing jumping passes, a skater does not get more points by doing the same jump singly and in combination; however doing jumps singly limits total points for jump passes, because of the Zayak rule and the axel requirement:
a. Without a 3/3 or 3A, the maximum jumps are 6 triples, one 2A, plus doubles in three combinations.
b. Without a 3A and one 3/3, the maximum jumps are 7 triples, one 2A, plus doubles in at least two combinations. All things being equal, base of 2.7-2.9 points higher.
c. With two 3/3's, the maximum jumps are 7 triples, two 2-A's, plus doubles in at least one combination. All things being equal, base of 5.2-5.4 points higher.
d. With a 3A and one 3/3, the maximum jumps are 8 triples and one 2A, plus doubles in at least two combinations. All things being equal, base of 6.7-6.9 points higher.
e. With a 3A and two 3/3's, the maximum jumps are 8 triples and two 2A's, plus doubles in at least one combination. All things being equal, base of 10.4-10.8 points higher.
That a jump receives the same credit done as a solo jump and in sequence is simply untrue and not a matter of opinion: a sequence, whether intended or called because of an incompete triple or quad combination in which a jump is repeated receives 80% of the score of a solo jump or jump in sequence.
As long as you maximize your jumping passes you can still compete.
It depends on what your competition lands. In Moscow, Cohen's competition:
Slutskaya: blew her out of the water, even with a jump repeated three times for which she got no credit
Kwan: didn't attempt to maximize jump passes
Kostner: didn't deliver the plan of record
None of Cohen's competitors in Moscow, save Kostner, has a plausible planned 3/3 combination. In Tokyo, the top four skaters either landed a 3/3 in the SP and/or landed 3/3('s) and/or 3A in the LP.
