What factors need to be considered when changing the default response timeouts on predictions in 8.5? One factor I am aware of is understanding that the longer the response timeout window, the more data needs to be stored. Are there any other general considerations?

One change I am considering is shortening the Predict Web Propensity window to 90 seconds or possibly 5 minutes (down from a default of 30 minutes). This seems more than sufficient for a real-time channel. But there may be a reason that a default value of 30 minutes was chosen.

Thanks!
