> 4KB/s (basically dialup speed)

I guess if "basically" means "takes 10x longer"?

32 kb/s is on the same order of magnitude as dial-up (56 kb/s), not 10x slower.

(I don't know if dial-up is still 56 kb/s these days, but that's the speed historically associated with the term.)

I was assuming that 4KB/s is peak speed, not sustained speed.
