Perhaps to those with lots of bandwidth, but I've got mine set at 2mbps and it's working well. Originally I set it at 5, and even 10. But those settings ended up using 20-25 GB in some cases. Set down to 2mbps and the same RV started using 10-15GB with no complaints coming from the occupants.
We only get 2TB of (Priority) data per month (Business plan) for $500 a month, so it's important for me to monitor the parks data usage carefully. If I have a lot of data left when we get close to the end of the billing period, I open up my default profile to 5 mbps, and sometimes more.
I'd rather my guests use it than to give it back to Starlink.
