@jbeale Welcome back!
Looks like your RF explorer has a slow sweep! Based on your description, it also looks like it's displaying an average of the RSSI's it samples over a dwell period before it moves on to the next frequency. Can you configure it to display the peak RSSI per sweep instead? It seems like that would make for a more useful display (though displaying both, one curve somehow superimposed upon the other, would be the most useful). Wouldn't you agree?
