did you type in your incomes on the cs calucalator (google it for your state...well or answerguy will have the expact place!)
ss during the divorce is sometimes not direct monetary, but maybe he'll pay 100% of certain supportive bills.
watch out. if he has his own business and income is 'flexible' his attorney may advise him to move the income to other avenues or advise him to 'slow down' the business so he will have less ss or cs to pay.
