In previous contests the rule was that the same trick could count up to 3 times, unless it was a regen trick and then it could count up to 5 times. And tricks done after a regeneration got bonus points. But those rules were first written when there was a single combined division and very few people could regenerate much. At worlds I did 5 repetitions of several regens (polar satellites, half barrel rolls, magnetic wire, etc) because those were the rules.
Now that there are separate divisions for fixed tip and bearing tip we probably need to change it so no matter the trick it can only count 3 times. A limit of 3 will give more variety to the fixed tip freestyle. However, I suspect some may struggle to find enough different tricks to do.
I would agree with yophosis that 3 MGR or 3 crazy-8 count as 1 trick, at least with bearing tops. I would give a wirewalker the same points as a corkscrew done with a bearing tip (you would be surprised, Chris, how many people find wirewalker much more difficult than corkscrew.)
In your example, Mike, you have a wirewalker so it has to be the fixed tip division. Then the corkscrew becomes a more difficult trick.
The points are normalized to 100 so it is not important what are the absolute points per trick but their relative weight.
I noticed that Chris did not say anything about not freestyling at Worlds, so I will include him on the list of likely competitors
Queen, you have enough chutzpah plus skill; that should be enough
