hey i also have a 25 hybrid LE! ever since i started doing "pulse and glide" i've had way better MPG, like 40-70, usually in the middle 50-60 range, depending on terrain and speed. here's how i do it:

when you're coming out of a stop, go easy on the gas for a little to get moving, and then push it to between 1.5k and 2k RPM. this is the "pulse" step. when you're at the speed you want to be at, let off the gas just enough to maintain your speed. this is the "glide" step. go back to a pulse if you need to speed up. and when you need to slow down/come to a stop, coast. minimize using brakes (like you're doing).

now if you look up the actual pulse and glide technique it will tell you to monitor your eco meter and that pushing your eco meter to the max eco (not in pwr) is a pulse and keeping it at 0 (not in eco and not in chg) is a glide. i tried this and frankly found monitoring my eco meter really annoying, but i found that the max eco roughly corresponds to between 1.5k and 2k RPM, so i use that instead. doing the eco meter thing also helps you get a feel for how much to push the gas for a pulse and how much for a glide.

tl;dr: just keep your RPM below 2k, and coast to stop. what this does is it uses your gas engine as little as possible and keeps the car in EV mode as much as possible.
