I get the same fuel consumption as you're showing if driven at 100-105 kmh. Put on a rooftop tent, 2 tonnes of trailer and drive at 110 then it really sucks down. While I'm Perth based, I originally used my D3 on gas pipeline work in Victoria, so took the opportunity to have the Long Range Automotive factory install a tank. It's worked a treat, allowing for 1200 km trecks. I don't recall the cost but it's around the cost of filling both tanks 3 times

Just a wee bit back towards the topic, my dad's '99 disco 2 has a very aggresive cruise too, on resume it basically accelerates at full throttle and then shoots over, then returns to the set speed. My '04 defender does exactly the same. Maybe it's a british thing!
I know the speed limit in the UK on most of the motorways is 70MPH, I'd be guessing that's what it's optimised for?

Yep, mine does that, perfectly normal behavior!

Just watch it doesn't get you a ticket!

I've recently started a new job and the route to work is a long country road (Hooray for me, no more SE Fwy

) sign posted at 70kmh which the coppers just love to set speed cameras on. So I use the cruise. On the flat its fine, but the slightest hill or dip and it's all over the place through over-aggressive gear changing.

At highway speeds I find the cruise great.

Mine's fine once set - rock solid, stays at the set speed.

It's the 'resume' function that gets a bit carried away with itself and generally sees you speeding momentarily. This is normal though, there's loads of stuff about it on DISCO3.CO.UK - Dedicated to Discovery 3 and LR3 Owners and Enthusiasts

Mine is no where near as agressive as the old TD5. The TDV6 does need more torque to hold a more constant cruise speed. I also have a little VW TDI (1600 kgs and 320 nm torque) and it is great.

Dealer told Me of this, whilst showing Me the rules of play, when I took delivery.
He said to accelerate up to 75% of the required/ set speed, with the foot, then let the cruise take over gently via the resume set speed function. He said to do it from much lower percentages would result in aggressive acceleration.

I have heard of this problem on the Pajero. In fact it was so bad that it caused an accident in wet weather.

I have fond that my cruise control will be anything from 5kmh fast to 5kmh slow when on the open Rd going up and down hills, I have checked this on the GPS so always set just below the speed limit by about 2kmh. Not to bad in Qld as you have about 5% margin but not so down Vic and NSW.
