Maybe someone can explain to me the scoring system but the way I thought I understood it a fall on a quad especially the loop, flip orlutz still scores you above many triples so itis worth it especially if it is in place of say a triple salchow or double axel - you will garner more points and probably not toake too much of a hit pc wise.
Well, it's really a question of fact, right? It depends on what the base value of the quad is, whether you fall, whether it's called <or <<, and what jump you're replacing it with. Here's the most recent (I think) IJS scale of values:

And here's the FS protocol from SA:

Looking at Jason's score, we can see he landed the 4T, but because it was called <, the BV was reduced from 10.3 to 8.0. He also got -GOE of 1.03, so the net value of the jump was 6.97 points. This jump replaced a 2A previously done in the bonus, for which the base value is 3.63. The maximum GOE on a 2A is 1.5, so the highest score he could get with all judges awarding +3 in GOE is 3.63 + 1.5 = 5.13. So even though his 4T was <, he still scored almost 2 points more on the 4T than he could get with a perfectly executed 2A in the bonus (6.97-5.13=1.84). If he had also fallen on that < 4T, he would have lost an additional 3.97 points (-2.97 in additional negative GOE and -1 for fall), so he only would have scored about 3 points for the 4T, and would have been better off pointswise doing a 2A in the bonus.
It's a similar exercise with Adam, who fell on a 4T that was called fully rotated. After factoring in the -GOE and -1 for the fall, he scored 5.30 points for his quad attempt. Since I think he was also replacing a 2A in the bonus, he still came out a tiny bit ahead (5.3 v 5.13). Looking at higher value quads, since a 4Z, for example, is worth quite a bit more than a 4T, Adam's < 4Z at 2016 worlds, which he stood up on, netted him 7.96 points (8.50 - 1.54 net GOE), nearly 3 points more than a perfect 2A. So it was even more of a no brainer to replace that 2A with the 4Z. I think that even with a << on the 4Z he would still come out ahead but I don't have time to do the math.
Obviously, if Adam was replacing a higher value triple with that same 4Z, there would be a less significant benefit. For example, his 3S in the bonus at Worlds scored 5.94 points (4.84. + 1.10) so replacing that 3S with a 4T / fall would not be worth it (5.30 for the 4T v 5.94 for the 3S).
