How is #4 smoothing ? how does it affect the numbers?

Possibly OK, the objective of smoothing is to average out the erraticpeaks and valleys in the line graph caused bydrive train, tire, dynopulsations for accurate, consistant numbers. If the lines are smooth, you know that the dyno is not clipping a high transient TQ/HP line graph spike and using it as a peak number. An unscrupulesdyno operator can practically provide you with any numbers you want by manipulating the dyno with different atmosphericand smoothing techniques. Example, if a dyno operator switches from SAE to STD correction, there is another close to 5% for TQ and HP.

I have taken my bike in several times, just for baseline runs. The price for just HP and Torque is $20 and $40 if you also want ARF.

I'm not sure if you want just the numbers or want the tune also. If you just want numbers, some dealers have special days that do just the run. I had that done on my bike. It was free. Try like a open house weekend or when a big sale and free road test are being done.
