It’s hard to say I’m afraid. You can almost certainly use it today as a reliable indicator of whether the RainCheck process has run, but you have to assume that it is at least possible that the summary object may change at some point in the future. You may have seen these comments from David: > [@Websockets Documentation for obs\_st](https://community.tempest.earth/t/websockets-documentation-for-obs-st/8276/4): > > Yes, the summary object is subject to change. Though it probably won’t go away, it will continue to change. Use with caution! > [@Websockets Documentation for obs\_st](https://community.tempest.earth/t/websockets-documentation-for-obs-st/8276/6): > > Yes, it’s accurate. It’s kind of a helper object we added to support the Tempest apps. so it may change based on the app’s requirements. We will probably need to solidify and document it at some point. --- _[View the full topic](https://community.tempest.earth/t/ws-obs-summary-object-precip-fields/9773)._
