Change in DissoMaster Spousal Support Calculation

I just sent a counter settlement proposal to my lawyer but overlooked an old DissoMaster printout which shows spousal support for $1200 over what I ask him to "try for."

How to read a DissoMaster printout? In Oct it appears there was a calculation for ss of 3193 but now, with a different lawyer I am offered a new printout with an ss of 1970 (that's with my job loss now). Are these dollar amounts and why such a difference? stbx has same income.   cs varies too, low of 548 in Oct. to a high of 1712 now.   Seems to me numbers may be changing to lower his payout to me.  Child support will only go on for a few more years while spousal support is indefinite due to our 16 yr. marriage.   Spaz help me understand what's going on and if it's to my advantage somehow
