So he is shaping down to  73.34% of his link, probably following the instructions from http://www.linksysinfo.org/index.php?threads/qos-tutorial.68795/ . From personal experience I can say that with cerowrt's aqm and the proper link layer I get decent latency results with just shaping down to 95% of link rate.
	I just checked and it does not seem that the current tomato fork he uses takes the link layer into account….  So trying cerowrt seems a worthwhile experiment for him to undertake. But from the writeup I assume he is quite happy as is and coming down from 32Mbit/s no matter what 1.5Mbit/s will feel slower.
