We're brainstorming some approaches in https://docs.google.com/document/d/18-HnOeQQUnQSRXxmsZkB-m4g5CcxHep7vixlJiHDmDw/edit. This ticket tracks the work to review that, flesh it out, and generally comment. |

With the spike wrapping up, it's not clear if this ticket should remain open and active while we have the context, or go into "hibernation" for a while before we get to the next proposed spike to investigate stats and histograms more. For now, I'll just remove it from the epic while I wait for feedback from our European colleagues. |
