Welcome to the forum, Harry.

The challenge, as you've pointed out, is that you're driving an automatic. That makes it more difficult to accelerate as efficiently as a manual because you have less control over engine RPM / gear selection.

Generally I think it's good advice to advise people with automatics (who aren't doing P&G) to accelerate gently.

Andrew's spot on with the advice for hills (also known as Driving With Load): the idea should be - where traffic permits - to monitor your instant mpg at that time, and modulate the throttle to keep it above some arbitrary MPG that you want to maintain. Depending on how aggressive you are with your target will determine how much you play (lift) the throttle and lose speed on the incline.
