regarding mommdc points
1 - Prior to 2016, ex-wife earned more, in 2016 she did not work for 1/2 of the year. that is why income was low. I guess she never considered herself poor to get means tested benefits. she made more again in 2017.
2 - yes
3 - end of year assets were $500 → 20%=$100
4 - yes, actually negative.which affects item 5 below
5 - disagree, Total allowances > 10500 (taxes paid + state tax allaowance+social security allowance+6570+allowance for parents negative AAI) So 16000-10500 = 5500, and 50% of that is $2750. I had just rounded that to > 2500.
I am pretty sure everything in the SAR is what was intended.
