Experiences with Mediumslow or Mediumfast compared to Longfast?

has anyone tried, changing a bigger mesh from longslow to medslow/medfast ?
that would offer higher data rate , so if you have a bigger mesh of 50+ devices (anyway many of these sending too many position- and node- infos…) , maybe that can work?

if there are no critical connections in the mesh, that require the range of long-fast…

what loss of range can be expected? if you have 20-30km connections with longfast, can med-slow do that too?

maybe thats an alternative to convincing all users to reduce their unnecessary broadcasting and setting low Hops…
