The limit is only when you use the query param generate_visualization=true (which is the default :)), since you dont show the visualization, e.g. you dont use our Tradeoff Analytics client side code, you should go with generate_visualization=false. If you do choose to use the visualization, please note that the the actual limit is feature* "top data points" < 2000. Your data points size might be 5000 and still our analytics will find that the optimal data points are just 100...
