Lobbies without fixed host VS Lobby with fixed host, tested as a single participant not host in post 24

Why this thread you ask? Here's why:
The purpose of this is, to see what connection you need to host a full lobby because fixed host lobbies seem to be more stable. you can read about it here
https://www.gtplanet.net/forum/showthread.php?t=168334
Thats why I initialy started this thread.
In essence it sais that:
a) in lobbies without a fixed host (normal open lobbies and the coffee cup lobby) the network type used by GT is a mesh network. Like a p2p network. Every player sends data to every other player.
That is why you so often see people in lobbies that cannot see or hear each other, you see people not beeing able to join the lobby due to incompatibilites between networks or people getting dropped mid race. that sucks.
b) in an open lobbie where you tick the box "fixed host" GT uses a Star Type network and the player who opens the lobbie acts as the central game host for every player.
So in case a) where every player needs to establish and maintain multiple connections to each other participating player in the lobby where some players have nat type 2, some nat type 3, some exposed host, some here some there some everywhere - basicaly networking is all over the place and a total mess. Hence there are so many problems with visibility and stability of the race. One player that lags can cause significant loss of race quality for every other player.
In case b) every player only needs to maintain one single connection to the hosting player. Like you connect to a central server and all player information and voice data you get sent from this single server. Once you established the connection dropping out or haveing problems is significantly less likely to happen as long as your and the hosts connection is not oversaturated.
Therefore these tests.
over the last two days I hosted two fixed lobbies for combined 7 hours. in this time arround 30-35 people joined and played in the lobby, a core part of arround 10 people for 3-4 hours minimum and I didnt see a single drop or any other trouble like people not able to see each other or the like.
Also i think for people with a slow internet connection it is better to connect to fixed host lobbies because you get a single constant stream of data that should be less than in a p2p lobbie. This is more likely the case the more players are in the lobby.

Hello
I searched the web but couldnt find any useful information regarding bandwith usage in GT5 online lobbys.
Say I host a 16 players online lobby with race and voice quality set to very high, how much upstream should I have? How much on high or normal? How much does voice chat add? And so on.
Is there any official information from PD on that matter?
i might add: what exactly is the difference between the race qualitay settings? whats different when set to very low or very high?
regards
edit: I've read a bit more and found theres a severe difference between fixed host and non fixed host, but failed to make out how I can set up a private lobby for my friends but with fixed host. Fixed host does only seem to be an option for open lobbys??
But there surely has to be a way to be the fixed host for a group of friends?
