A disc first has a POSITION in space once thrown per 802.01 A "A throw is the propulsion and release of a disc in order to change its position." before a LIE is marked. Rule 802.06 provides two options for marking. "A. The POSITION of a thrown disc on the in-bounds playing surface marks the lie." i.e., the player may play behind the previously thrown disc leaving it as the marker.
"B. ALTERNATIVELY (this is the key word), the player may mark the lie by placing a mini marker disc on the playing surface, touching the front of the thrown disc on the line of play." There's no requirement that it's the same playing surface height as the surface behind the disc, but simply the playing surface below (usually) the position of the front edge of the disc regardless whether that height is right under the front edge of the disc, a half inch under it or 10 feet under. It's similar to the way verticality is used for 1 meter from OB on a slope or marking a disc suspended above a playing surface.
We know there are exceptions for the mini to actually touch the thrown disc. To reduce confusion (or would it increase it) perhaps the rule should say the mini must touch the virtual vertical plane at the front edge of the disc?
Chuck, you KNOW I agree with you most of the time. And I respect your close-knit participation with the rules committee, comp committee, and as a PDGA liaison over the years. If you know something OTHER THAN the rule about "disc above or below the playing surface coming about to address discs falling into a crevice in the parts of the country that had great droughts for a period of time, (I say other because they might be RC having other intent), then please let me know. Otherwise I still see it both in intent and actual reading that I disagree with you herein. The intent one is easy – if the RC intended that you could mark on either surface even if your disc was on one surface they would have said so. I don't think that is the case unless Chuck you'll enlighten us.
Now how do I disagree with what you've written here, and what the rules say as I read them, cgk? Classic "em-PHAS-sis" on the wrong "syl-LAB-uhl." The KEY WORD isn't "alternately"; the key word is "may" as I read it. Meaning you may or you may not. There might be another option or there might not. If you emphasize "alternately" then I get your point. But surely the fact that it says you "may" mark a different way DOES NOT mean it
guarantees you that way. It is an option for you when (and if) that other alternative option is available. In your response above, like many others, you go to the marking issue before ever determining the disc's position. Determining the position has to come first, and in the OP it is my distinct belief that the disc is ON the playing surface. Convince me otherwise and I'll be willing to hear other sides. I just have yet to hear anyone put forth any evidence that the OP's disc is anything other than ON the playing surface.
Those who say the OP describes one continuous, contiguous playing surface then there's nothing else but "THE" playing surface in this OP. Those who say there are more than one, then that would mean reverting to vertically-stacked playing surfaces applications of the rules.
You are misreading the OP- it quite clearly states that PART of the disc is on the upper playing surface but not all (and not the relevant part for marking)... (and I have been stating this all along)...
How am I misreading "on"? That's the word both the OP and YOU use in the description (as you did above). With 805.01 A, this is very clear.
I know some people like to either "skip over" this fact or "move past it" to the "marking issue;" however, first things must come first. It's ON. Not in a bush, brush or tree suspended above a playing surface. It's ON. Its position (by 805.01 A), and anything sensible says it is ON the playing surface.
You understand the difference between "stand" (your word, not mine) and "stance," (my word, used throughout the Rulebook), do you not?
Regardless of where you mark a lie, you are REQUIRED BY THE RULEBOOK to be able to take a legal
stance at ANY lie in order to play from it.
And that's my point. Anyone claiming he cannot "stand' there is making an invalid point. The stance may or may not include "standing." I've yet to see an example (maybe there is one but it'll be rarer that these rare ones on this thread) where the player cannot take a legal stance according to the rules and throw from the lie on the same playing surface (level) as the thrown disc. I'll even make a video for you, if you'll make one of where the disc you want me the throw from is.
and ps, sorry coupe, I'm answering where I was quoted. I'll read the rest of thread since later today or tomorrow.
