Impossible MPG figure

[Barry14UK]

After I refueled last,  I pressed the mouse like controller and when I looked awhile later, the pictorial column was at the top and the figure given  99.9mpg which still shows as best figure achieved after maybe a 100 miles or so.  However, the running figure reduced quite quickly, and due to recent journeys being fairly short, the current active figure is about 24mpg.  Clearly, in reality my car was never achieving 99.9mpg which still shows as best result.  Could this have been because I touched the controller fairly soon after refuelling or is there a problem with what has been recorded would you think?

About the same MPG as I get from my 350!

On my GS450h, this number resets whenever you refuel.
So if you just refuelled, then moved off on electric power the maths says =>
000.1 mile / 0 galleons = TO INFINITY AND BEYOND!!!! 😉 Or 99.9 which is as high as the number goes ;)

Thank you, so seems normal then, although this is first time in 2+ years this has happened, so I thought worth asking.

Just a thought Barry - - - did you refuel at the top of Ben Nevis?

Ha ha!

Not even trickling down the famous Porlock Hill LOL.  Still if that 99.9 best still stays on it when we part company, (which hopefully will be a long time hence), somebody else is likely to wonder how the figure could be achieved.

On my ES (weather permitting) I have seen sustained readouts between 80 and 100 mpg.

Here is an example.
