Thanks, I was curious as to what it topped out at.

Can't wait til more HCH II's break-in. I see more than a few people at 60+ spring mileage around April. Let's keep our fingers crossed.

Just FYI...

Following my Prius II data driving on a highway at 91km/h using CC.

point_____ODO__disp_km/L__calc_L__sect_L__sect_km__sect_km/L
================================================== ==========
Point-A___88km__28.6km/L__3.08L___0.00L______0km
Point-B__116km__27.7km/L__4.22L___1.14L_____28km___24.53km/L
Point-C__131km__27.1km/L__5.02L___0.80L_____15km___18.73km/L
Point-D__193km__29.5km/L__6.54L___1.52L_____62km___40.70km/L
================================================== ==========
Note: calc_L=ODO/disp_km/L

Additional information...
You can see very various section mileage number even driving at 91km/h constant speed.
The reason is there were altitude(potential energy) changes.

Assuming we need 106mL gas to get the potential energy for 100m high, I did math as follows...

point_____Alt__AltChg_m__AltChg_L_adjust__sect_km_ _adjust_km/L
================================================== ==========
Point-A___634m_____0m_____0.000L__0.000L______0km
Point-B___761m___127m____-0.135L__1.007L_____28km___27.82km/L
Point-C__1009m___248m____-0.263L__0.538L_____15km___27.88km/L
Point-D__ 346m__-663m_____0.703L__2.226L_____62km___27.85km/L
================================================== ==========

Then, the adjusted section mileage number is constant like I drove very flat road.
Also, the 106mL usage to cover 100m alt change means the system thermal
efficiency was more than 35%, which is very good!

Enjoy,
