To me, this recommendation does not seem to go with he rest of your post.
If a wrong edge take-off is just another errror, like an inside edge landing, or a hand down or step out, why shouldn't those other errors recieve a 10% reduction in base value, too?
Those errors are on a sliding value between however many judges are judging, rather than edge and underrotation calls which are simply called as a set thing by the tech panel.
So, if you keep that balance of power between the judges and the tech panel, an edge mistake should be taken off the base value because of the fact that falling on a Flutz should (IMO) be worth less than falling on a Lutz. Currently, there is no difference. The Flutz deduction is simply part of the already maxed-out negative GoE given for the fall.
It seem to me that you are implying that the Flutz is a legitimate jump You would have trouble convincing the ISU of that.
Is a double-footed Lutz, or any other double-footed jump, a "legitimate" jump? Why is it that such a thing is not given 0 points, as you think should be given to a flutz?
A Flutz is simply a deviation of technique, not an illegal move. It makes the jump relatively easier...and that's it. The difference is this particular error has been given a notable nickname.
A Flutz or a Lip can still be a beautiful and challenging move. For those who aren't blinded by simple hate/bias, I would say to look at Mao Asada's Flutz. She does intricate footwork into it, gets very good height and distance, has a good air position, and lands with good flow coming out. I prefer her Flutz to a Lutz from many other skaters. Similarly, I'll take Joubert's Lip over a Flip from most anyone else.
What this argument really comes down to is the following line of thinking: "a Flutz is a Flip, and a Lip is a Lutz".
That statement simply doesn't hold validity in my mind. It's joke to me for someone to say they are the same movement. If such a thing were true, I'd love to know why they feel much different when skating. Why is it that they don't gain momentum in the same manner?
No, a "Flutz" is a Lutz and a "Lip" is a Flip. The entrance remains the same regardless of the blade shifting over. A Lutz with a hand down on the landing is still a Lutz too. But, you give something a name and it takes on a larger importance. If only I had a name for "crappy spin position" that rolled off the tongue like "flutz" and "lip". Maybe then those issues would be cracked down on. I love how ISU's remedy to all the horrible spins we are seeing was to cut the number of them allowed from 4 to 3 in the Long Program.
I've never had a problem distinguishing a "Flutz" from a Lutz or a "Lip" from a Flip when watching the skater go into the move. Did they enter from a back-glide/counter-turn/walley (Lutz) or did they enter from a 3-turn/mohawk/half-loop (Flip)? The edge of the blade on takeoff doesn't determine those movements and if anyone is able to do at least a double of each of these jumps then they should know how different it feels.
