depends on the QoS. Hence why manually setting your QoS is usually better. Bufferbloat isnt easy to measure either. Lets say you have a QoS that gives priority to video over web. You watch a video and run a speed test, the speed test shows your bufferbloat as F but your video just kept streaming without any buffering, interruption or such.
This is because bufferbloat is highly dependent on the packet managing and QoS. For instance, the simplest way to check for bufferbloat is to ping and use up all the bandwidth, and the ping times will increase but if your QoS gives the highest priority to ICMP, the ping times will be the same when fully using the connection.
