[Organizers] Performer "Testing to Unmask" Policy Timing

For those of you with a COVID policy regarding testing (particularly re: performers "testing in" to be on stage unmasked) - please consider your lead time and possibilities for contingency action. We'll be changing the policy of our dance due to our experience tonight. Our caller (me!) tested upon arrival at the hall. Entered masked, helped get set up going and then discovered a positive result. Thirty minutes to the first dance, folks already en route. Best efforts made, the dance was able to happen without me but just barely. We will be requiring this optional testing now to happen within a specified period which will provide for sufficient time to react appropriately before the event set up commences.
