very well demonstrated thank you for making this video

Nice explanation. Something that I wasn't overly familiar with. Gives a bit of insight into why "X" manufacturer has taken a specific route into combatting tracking/anti skate...and others follow "tried and tested" methods... Ultimately the research and design elements are seen in the cost to manufacture and distribute...

My understanding of the overhang/offset angle design is that they are able to make the stylus angular error in the groove zero at two points in rotation from edge to center and small angles everywhere else , It seems the Viv design creates perfect tangency at one point near halfway across the record with increasingly higher angular errors the farther from that midpoint the stylus moves . It looks like the Viv nearly solves the skating problem at the expense of more angular error to the groove . Both approaches seem like one step forward and one step back . A perfect linear tracker may or may not be possible , but I'd love to see one some day . There is a German electronic linear tracker accurate to a micron , but it's $150,000 .

You're absolutely right- overhang/offset reduces tracking error but introduces a constant inward skating force that needs to be countered with anti-skate. The ViV Lab arm allows the tracking error to be higher with the benefit of better lateral stability (near zero skating force and no opposing left-right forces affecting the cartridge). All designs have a compromise somewhere, including linear arms. You're right that linear arms solve both the skating issue and the tracking error issue, but the compromise there is less mechanical efficiency, chatter, friction, etc... no matter how high the price. All designs categories can sound great though, if they are smartly engineered and well-tuned.
