What is a good CS on contracts?

I’ve been back enjoying egg inc over the last few weeks and the new contract format is still confusing to me. What is a good CS? I’ve been in AAA contracts following the discord and other reddit page and went from 10-15k to hight 30’s mid 40’s now. A few contracts in the 80’s. Is this average? Is this a good range to complete the seasons? Should I spend the time redoing contracts for more?
