Also, the highest wifi speeds are only achievable with build traffic to a single client (or with mu-mimo to a small number of clients), it's not that with n clients, each gets anywhere close to 1/n bandwith. And if you add a single slower device to the network, it will eat much more airtime than it's bandwidth would indicate.
