It won't be a jumbled mess, at the most the offset will be about 30 degrees for the painting radar until you return to level flight. Even modern RWRs aren't "magical" know-it-all detection instruments. Even current DCS level modules have big gaping blind-spots in their RWR detection systems, which is exactly as it should be.
With that said I do have a question for whoever at Heablur is coding this: What kind of performance hit will this kind of detail add to the simulation, if any? As a followup: Do you guys balance performance vs modeling detail during the coding of your modules, or do you just go all out on the modeling and let the performance be whatever it ends up being?
