I had 99.9 on my VR6

Same as you, except reset MFA while foot off throttle, just letting it roll on a dual carriageway (there was a roundabout in a few hundred yards so I was just letting it slow down well in advance).
Sometimes I try to see how conservatively I can drive it... on an average journey of 10 miles or so I can generally get over 33MPG if I'm careful, but that's no fun. Normally I'll get around 25MPG out of a tank on average.
