I had the RAC out repairing my car a little while back and he said that the
ECU 'learns' your driving style and adjusts itself accordingly.

I have noticed with my car (2004 1.4 Petrol Ford Fiesta Zetec) that
sometimes the acceleration seems more urgent than it does at other times.
In recent weeks I've been trying to save fuel and driving economically, and
I've noticed the acceleration was a tad sluggish when I put my foot down.

However yesterday I took the car out for a quick blast down the motorway, by
the time I got back I found that it seemed to be accelerating a lot faster
and just seemed to have more power in general. Could the ECU have switched
modes from economic to performance somehow? Or is it just all in my
imagination...

The ECU does alter its settings according to driving style in exactly the
way you say. The car wont actually be faster or slower when given full
throttle, but it will feel 'numb' to the pedal after a period of being
driven gently / sedately, and more eager when shortly after you begin to
drive more aggressively.

My Focus is exactly the same.

My car feels sluggish as hell lately - my wife has been in the passenger
seat for my last few journeys!!!!
