I imagine that depends on the nature of symptoms and behavior of other causes of the same symptoms. For example, if we assume that we have regular flu and covid, and both cause cough, and we only test people that cough, then we're just measuring relative speeds of spreading of covid and flu, and if flu spreads more actively (just for the sake of example) we'd have a drop in covid percentage.
Also I'm not sure the criteria are even static. I.e. if they had more capacity (and the capacity, as far as I know, does increase) would they test people with less severe symptoms? I dunno.
