A few comments on this.
1. There was ZERO discussion of outdoor minyanim with Dr. Fauci. That is extremely surprising. Having his expertise weigh in would be extremely helpful to many communities in creating interim guidelines. The OU themselves discuss this option and how they will be issuing guidelines. Why wouldn't they take advantage to get his input on this?
2. It seems that his main concern was how many people would be in a shul at a given time. He has no discussion of what, if anything, should be done between any staggered minyanim.
3. With staggering it should be able to be arranged in amny places to have multiple minyanim a day and keep to distncing.
