This will vary depending on many factors; type of force application, your level of relaxation, amount of local inflammation, joint degeneration, your history of being adjusted, history of previous injury, hydration, just to name a few. The adjustment may utilize a more traditional force application or more subtle adjustments to the tensegrity of your body. With a traditional adjustment, you can expect it to feel like a quick, deep stretch. This is typically not painful; however, if there is pre-existing injury or inflammation near the segment being adjusted, you may notice a brief increase in pain before it improves. I also utilize low force contacts when adjusting subluxations in the soft tissue

This depends on your goals. If you are here to resolve a condition and that is all you want, it will depend on the condition. If you want to use chiropractic to improve your overall wellbeing throughout your life, this is a life long commitment. I myself am adjusted weekly.

The sound you hear is gas moving within the joint because of a temporary change in the pressure in the joint. This is somewhat similar to opening a can of soda. This happens anytime a joint enters what is called the paraphysiologic space (more than passive range of motion but not enough to harm the tissue)

I occasionally use drops in my osseous adjusting. They are sections of the table that raise by an inch or two and drop when I make an adjustment. This lets me take advantage of inertia and use less force to adjust. There are some adjustments that would be very uncomfortable without a drop (trust me, I’ve had them done.) or would require a different positioning.

I use leg checks for many reasons. Most people have a functional leg length inequality or FLLI for short (one leg appears significantly shorter than the other even if it is not).  The FLLI gives me suggestions on where we should start when adjusting your spine and can be used to confirm a particular subluxation’s characteristics before putting a force into it.
