@MS I don't think you can look at a new 10m (-42') length as simply some kind of easy formality for CP and Nate, some inconvenient new hurdle they've got to bang off so they can get back to chasing the 'real' record. To our knowledge, no one has ever run 10m (-42'); no reason to expect it to be easy (or even possible). What you might expect is that somebody might get further than 1, 1.5, 2 balls, and THAT would be good for the sport in the long run.
As much as @ral makes a good point about the world's patience with long-standing high-jump records, I think the main issue here (as we approach the physics-based limits of the sport) is that some well-intentioned folks - many years ago - decided (for simplicity?) that after -38/11.25m, we'd just take off 0.5m every time someone makes a pass. Time has passed, performances have improved and we're now at a point where it makes sense to question that decision (people running -41 pretty often but no one ever getting a look at 3 ball @ -43, barely getting a look @ 2 ball). I think a 10m (-42') would make elite tournaments way more interesting for the next 10 years, and I think THAT would be good for the sport.
Speaking of things that would be good for the sport/tournament-drama, opening at -32' at elite OM tournaments is also something that should probably change.
