I have talked this with our RD just now
the buffer bloat of D5 is more serious is caused by its higher upstream speed
other routers with lower upstream speed will perform better in this buffer bloat test
so we think the buffer bloat is not a fatal point
as you mentioned that customers with buffer bloat issue also suffer when surfing the Internet , we can collect more information for this issue,
the grade or result of the bufferbloat isnt very meaningful because it has connection with the current upstream speed during the test process, D5 V2 has higher upstream speed and it has the worst grade”
