That's a very good point. Let's see, other short programs with the typical 3-2, 3, 2A layout get around 60, some a bit above, some a bit lower. Now deduct from Kim's 76 points the Triple Flip, perhaps she pops it, - still 71. Let's say she pops the Flip and falls on the 2A - we are still at 67 points. Let's say she pops the Flip, falls on the 2A and on the 3T at the end of the 3-3. Makes 63 points. Now we are close to the highest scores of the other ladies this season. I know that it's not done this way, and that a program with such three glaring mistakes might also get lower PCS. But it's kind of scary nevertheless.
You are forgetting about the points she would lose from the +GOE she would normally get from those elements as well.
Popping the Flip would be -6.5 on the tech score and a small deduction in PCS. If she also falls on the Double Axel, that would be about 5 more points off from the tech score and a sizable drop in PCS. She would score about 61 points with those two mistakes (and possibly not make the final flight of skaters).
