Your mixing up 2 scenarios, methinks!
Skipping moves is plain obvious, your missing out on the climb... (Read: Mandala starts low, if you gotta stack pads, your skipping moves.) But it sounds like in your example your friend used the same start hold as you did, only matched it instead of using the arete (which is never used again after the start, so the arete should be its own climb), so dont confuse the two arguments.
If someone starts a sit down standing, they are not doing the climb.
If someone starts two moves PAST the start hold, they are not doing the climb.
If someone matches the start hold, instead of starting one hand on that hold, and one hand on a higher crystal, THATS just preference (and common sense.)
Heres a good example: "Joe Boxer" is traditionally started with a double heel hook. Something I find terribly flexible and crazy. So, like many others in the community, I heel hook left, and toe smear under the heel instead. Makes more sense to me, and your still starting with your hands on the same start holds, and your butt on the ground.
Another example: "Exciter" starts with left hand crimping and right hand on the arete pinching, right? Theres two or more crimps on the face to grab with your left, it doesnt matter which one you use, not to mention if someone actually found it easier to start matched on the arete where you rright hand is, why not?? I also watched three different climbers today all start "Tough Sailors" "legally" in completely different ways. 1 with an undercling and sidepull, another with hands crossed, another with both hands on sidepull. All worked, all were fine.
Some climbs
are contrived and have specific intention to be weird or inobvious though. Also, some dyno's are contrived cause there are easier ways of solving them....
like "Blacksmith" as a dyno is V9, but you can actually mantle the crack and make it V5. So if you do it the easiest way, you are not doing it the way it is graded and intended by Zig.
haha SO in conclusion.
your silly homemade problem at Prospect was contrived to state where your right hand must start, and I used the same start hold you did with your left, buddy!!! I just found better beta and matched instead of the one-time use of the arete, which made no sense for the movement of the climb....
But thats ok Mike, we all make dumb climbs. Apparently everyone hates "Fruit of the Loom" in Gibralter. I still get dirty looks for that one.
