I did something similar when she wanted "Spousal Maintenance". She signed that away for the low low sum of $2500.
Right after I was told by the County Mediator in the same building as the courthouse that, "Ohh you are in the military? The judge will never sign off on you getting more than 49% parenting time." Ohh but I as the father sure as hell can work full time while she is allowed to work part-time and have an accounting degree and work on a second degree.
I stand corrected, I edited my original post.
