If you want fairly flat power for beginners or for really slippery conditions then you would set the bike up with a “low” compression insert. If you want to keep the bike standard, order the “standard” insert. If you wanted a more aggressive power setup, or you are going high in altitude then you could experiment with a “high” or “very high” compression insert.
