Chris,
Do you have a data logger? The rule of thumb is from the time the driveshaft starts moving til the engine and input shaft are at the same speed. More than 0.6 is too much, and less than 0.15 is not enough. This is just the launch. Each gear change you want to see some slide, particularly high gear. Base adjustment is for the launch, and CW adjustment is for high gear lockup. But CW will impact the base adjustment. How much the clutch is pulling the engine down is another factor too. Not sure if this is helpful or makes sense. There is also too much slip that can glaze the disc, and it will not lockup the same after being glazed.
