I think the new base values for those jumps will definitely help Jason as it diminishes the importance of those quads. Maybe cooler heads have realized that men's figure skating (and apparently women's as well) is becoming more of a jump exercise and less of everything else. I think going to the extreme isn't always good. I think any quad is beautiful if it's done well. Most of them aren't done well and can ruin a program. My opinion, of course, but there are many fans who disagree with me. I like to see a well-balanced program with a sense of musicality and nice presentation. Not everybody is going to be a Jason but there are many who can at least strive for that level of presentation instead of just going out and zooming from one jump to another with a poorly executed spin in between. By lowering the base value of a few quads it might force skaters to only put jumps in their programs that they can actually do. I've never agreed with giving points for a failed quad just because it was attempted.
I think the mandatory GOE -5 for a fall on a jump has already moved things in that direction. The latest changes won't make as much difference at that one did.
And I agree that a bad quad is a bad jump. I think GOEs for quads are generally too generous. And don't get me started on the effect of quads on PC scores.
