I've always been of the view that this is the general direction that things will go in the long term. In the short term, the issues are cost and institutional inertia. A related issue is that it doesn't make sense to install such elaborate systems just for measuring the rotational acceleration of spins. It would have to be in the context of a more wide-ranging technological overhaul of how skating is judged and presented. (I think I wrote a speculative piece on this a while back)How do you get stricter on something as objective as speed? If it's still arbitrary, then they should start measuring RPM and stipulating the RPM increase required to count as "clear" - we have video recordings and image analysis software for this kind of thing. The technical panel can just be there for ensuring the software hasn't been fooled.
