ITA w/ KAI. A MAP score of 220 is actually a very good match for 4th grade level math. It means that she should fall around the 89th percentile of a typical regular class. Since these are GT kids doing a one-year acceleration in math, she may actually have far more peers at her level or above, perhaps a quarter or a third of the class.
50th percentile actually indicates insufficient acquisition of skills, particularly in a high-performing school where that same score may be a significantly lower percentile. In your DD's case, at least based on her MAP score, there is still room for improvement at the 4th grade level. Rather than acceleration, I would instead focus on solidifying and deepening her understanding/mastery of 4th grade math. It appears that her teacher did not take your request for a double-acceleration seriously. Perhaps if you approach the teacher with a request to strengthen your DD's grasp of 4th grade math, you might get a more helpful response.
Do not despair as it is entirely possible to maintain 98th percentile with just a one-year acceleration in math, although you would need to have a very strong grasp of the math that you have covered. I would also not be too worried with a stagnant winter score as due to different order of topic coverage, among other factors, the year-end score is often more telling than a mid-year score.
Ultimately, you can also spend an hour a week with your DD to strengthen her math skills. At this stage, you are still dealing with elementary math so unless you are math-phobic, you may be able to help her just as well as the teacher.
