Tonearms without anti-skate, damage to records?

1. Few people mention the VERY IMPORTANT lever force of the cantilever/coil former on the coil damper. There is a 6:1 lever arm there. So, if your arm has ZERO internal torque forces prior to anti-skate application and you decide you won’t use anti-skate force then you can live with the following: skating force is ON AVERAGE, 10% of your VTF. If your VTF is 2gm then there is 0.2gm of horizontal force at the stylus. Multiply that by 6 times to determine the force on one side of the damper and -6 times on the other side of the damper. That is 1.2 and -1.2 grams of asymmetric force applied on the VERY critical coil damper - 60% of your VTF! The sound of alleviating this force is unmistakable: more relaxed sound, larger soundstage, more overall coherency and intelligibility.
2. For those who say it doesn’t make a sonic difference, I cannot argue with them because we cannot know what their STARTING horizontal torque force was. Unless they used a WallySkater to measure their starting torque, neither can they. If their starting torque force was, say, 5% towards the spindle and then they applied a 15% anti-skate force then the absolute net asymmetric force would have remained unchanged. There are several scenarios like this that reduce the benefits of utilizing the anti-skate mechanism. You NEED to know what your starting and ending torque is to make sure you have it applied properly.
3. Watch THIS VIDEO at about 7:00 showing the angular effects of skating force. This was done on a 12" tonearm. If I had done it on a 9" arm the angular change would have been even greater.
4. This angular change affects the alignment of the left/right contact edges of the stylus in the groove wall to a greater degree than the maximum angular error across the record surface. The mechanical cost of this is easily measurable and definitely audible under controlled tests.
5. Worries about asymmetric stylus wear are founded. When I get cartridges in for analysis I can easily see whether they have been using too much or too little anti-skating force.
6. Watch out for high stiction in a tonearm. This will also kill your anti-skate benefits quickly. I know of one expensive arm that has a magnetic anti-skate mechanism that creates its own VERY significant stiction. The WallySkater measures this as well. More often it is in the bearings where the high stiction deteriorates the ability of the cartridge to perform at its maximum.
7. There’s more, but I’ve not the time...

Dear @rauliruegas 

If you give me a $100 bill and I were to exclaim I am now $100 richer, that claim might be untrue because I didn’t notice you may had taken $200 from my back pocket while giving me this one hundred dollar bill.

I.E., One may not make any claims about the sonic benefits of anti-skating before first measuring the starting horizontal torque force AND the arm’s static frictional force. Starting horizontal torque forces and stiction can vary wildly by tonearm - even of the same brand and model (to wit: those who were at AXPONA and witnessed the problems Michael Fremer had with the tonearm suppled to him for his setup seminar.) This is why the WallySkater was developed: so we can REMOVE THE VARIABLES  from our assessment and apply the best AVERAGE compensatory torque force to keep the skating force from inhibiting the performance of the cartridge.

additionally, if your tonearm has significant horizontal torque native to it before applying AS, then you can be sure your cantilever alignment will be off as well
