Seems chat is reporting the speed at which the serial port is
talking to the modem. When compression is enabled, this can
be 2x the actual connect speed, or even more. The serial port
speed is what you configure in the pppd/chat options; the modem
buffers data and/or manages flow control as necessary to make
everything work.
Simple way to find out the real connect speed is to make chat
run in verbose mode (-v will do it, I think); make sure extended
responses are enabled in the modem init string (this is somewhat
manufacturer specific, but I think something like AT&X4 will
usually work); then look in the log file for a string starting
with "CONNECT" - the number following is the negotiated line
speed.
