You are welcome. Adjust compression (and afterwards, rebound) until you are satisfied with the car's responsiveness AND the ride is comfortable for you. There's a balance between ride comfort and handling, so if it feels too stiff, then it is and you should reduce compression. And if it's harsh, you should reduce rebound. There is a difference between harsh and stiff.
Don't worry initially about 'getting it right' - the dampers are adjustable and you can adjust them at any time. I guarantee your preference will change over time. You won't know what is 'right' (and I say 'right' loosely because as I said, driver preference is key) until you try some settings, go with it for a while, then adjust them again (it's good idea to write the settings down in a notebook - be sure to note your tire model and tire pressures too). The same settings won't be ideal everywhere - e.g. really stiff on a smooth track is great but on the street ... nah.
Sooner or later you'll understand the setting's effects, and neither I nor anyone else can give that experience to you in text form. Kind of like riding a bike.
Good luck out on the track, be sure to tell us about it. There's usually a ton of knowledgeable and kind people at HPDE events (especially BMW CCA) - get a ride with someone and just have fun.
