A bit confused on best way to pulse

It kinda depends on how far you think you can glide. If you pulse with a 20 mpg average then you will have to glide further than if you pulsed with a 30mpg average to acheive say 100mpg. Most say you should keep rpm around 2100-2200. Or you can go by the guideline of keeping mpg at least half your mph.

Have you watched this video?

The best way to pulse is at about 75-100% of the Eco bar, or as you put it, the upper half of the ICE region. FYI, contrary to what you have read, it does not necessarily send extra power to the battery. It is more efficient than pulsing slowly.

At lower speeds (< 46 mph), it is best not to drive just slightly past the midline (50-55%).

The pulse zone in that image you posted is the correct area to be when pulsing.

 

I agree. The US Department of Energy did a study on the
2010 Prius and determine when the ICE is fully warmed up
that its most efficient operational range is from 1250 to 1600
RPM. this corresponds to about 60% to 90% on the HSI
Eco bar(or between .80 to 1.20 gallons per hour if you have a
scangaugeII) . In this range the Prius ICE is has about a
35% to 38% gasoline energy to engine output power
conversion.

However, the most important aspect of the pulse
is the final speed you reach at the end of the pulse, because
you don't want that speed so high that if you have to
stop that the you lose too much energy - which is an
important factor in urban/suburban driving where there
are alot of events that may require you to do a full stop.

In non-stop flat highway driving, wind resistance tends to
limit the effectiveness of P&G to a top speed of about
50 mph. A long downhill grade or a tailwind can make
all the difference here.. The trick is being able to identify
when you have a tailwind that you can use...

P&G produces its best fuel efficiency results on
empty flat country roads if you can pulse to
a top speed of 38 mph and then glide until you get to
about 23 mph and then repeat over and over again.
At under 40 mph - wind resistance is less of a drag.
It seems to me that when the ICE is running at the
low end of its most efficent power range on a flat
smooth surface the Prius tends to slow tread
up to about 35 to 40 mph

Ideally the top pulse speed is 38 mph, the Prius is
warmed up, the outside temperature is 72 F degrees,
there's miles of flat very smooth asphalt road in
front of your car with no traffic, the Prius is fitted
with low rolling resistant tires, the tires are inflated
at the maximum sidewall pressure), the windows are
all rolled up, the AC/heater/defroster is off, and you
have a tail wind, and you have a tank full of 100%
gasoline. If you have slightly hilly roads then try
to synch each pulse to a downhill grade section of
the road and try to glide on the uphill.
