Stylus-Drag..Fact or Fiction?

OK, enough BS about setting RPM with or without a record being played. Any decent TT has one of several motor-speed control methods to lock-in on or close 33 1/3 (or 45) RPM. Having arrived at "any" RPM setting/value the motor-speed-control compensates for stylus drag or lack thereof. That's why its referred to as speed-control. The Raven exemplifies the precision of its "speed-control" in the video. Because the laser point "changed position" due to stylus drag or lack of is only proof of its existence for that brief interval before compensation is made. If the RPM be exact the point after negative feed back should remain steady which it does. Because it has moved to right or left is not an argument but holding steady under varying loads is testimony to the TT's motor-speed-control's accuracy. The beauty of the Timeline is to allow you to set the Raven's RPM as close to 33 1/3 as possible and doing so with or without drag is BS. Video shows the laser point holds rock steady 33 1/3 RPM under all conditions including no drag. If the point moves with each subsequent revolution of platter it indicates other than a 33 1/3 RPM but says nothing of the TT accuracy of holding a desired higher or lower RPM setting. That's what's important.The timeline is nothing but a clock flashing every 1.8 seconds. Stick your finger on platter and you change laser point position and MSC should keep it steady where ever this dot ends up. Because the dot has changed original position only indicates a sudden load event has occurred. If perfectly set at 33 1/3 and dot is stationary after initial load change dot on wall will remain at position. A movement of dot merely indicates other than non attainable perfect RPM which isn't the most important thing here.
