There maybe hard limits depending on solar panels power available and the radio setup on the satellites. My guess the tolerance is lot lesser than 10:1 . SpaceX likely did some load tests before opening up roaming, so must be confident to some extent. They are also adding satellites every week so capacity is likely also improving. The dish manufacturing constraints and base stations could be other limiting factors for duration of waitlists
