TomTom not finding fastest route

I am still using a Go Classic and have come across a new problem since my latest map update.

If I use "prepare route" and find the fastest route from Le Havre to Arnage it takes me via Caen in 2:42hrs and 159m.

If I then find an alternative route via a point that I have defined on the A13-A28 junction I get 2:34hrs and 156m.

Any ideas what is going wrong?

I am using OS 7.903 and map Western_Europe_1GB v870.3417.

I can't get my W&C Europe map (870.3391), to find a 2:42hrs and 159m route. It finds 2:34hrs and 156m the first time, and any alternatives run into 4hrs plus.

There might be a data error in one of the one-way streets, of which there are many, in Le Havre. But it's unusual to find the alternative shorter AND quicker.

Out of curiosity, I used Microsoft Autoroute 2010 to plan the route.

It uses TeleAtlas maps, and gave the following results for the quickest route:

137 mls 2h.26m
