As I understnad it, 802.11ax can do 16MB (4MB to each of 4 different endpoints)

This is made significantly messier because the headers for each transmission are 
sent at FAR slower rates than the data can be, so if you send a single 64 byte 
packet in a timeslot that could send 4/16MB, it's not a matter of taking 
1/128,000 of the time (the ratio of the data), it's more like 1/2 of the 
time.

So it's really valuable for overall throughput to fill those transmit slots 
rather than having the data trickle out over many slots.
