Trafffic Auto-routing

[Ains]

Can anyone confirm that I understand something correctly (or not) :

If I turn on "automatic replan" in the traffic settings, TT will re-route around any traffic incident regardless of the time delay for the incident (i.e. it will plan an alternative route even if the alternative adds more time to the journey than sitting through the original delay)

If I use ALTERNATIVE ROUTES then MINIMISE TRAFFIC DELAYS, TT will only re-route if the alternative is quicker than the original including the expected delay.

Is this correct ?

Also, has anyone else come across TT sending them off a motorway at a junction and then straight back on, instead of just continuing up the motorway ? This happend to me twice tonight on the M25 (and no, I didn't actually go off !) between the A1 and the M11 juctions.
Thanks

So to confirm, both methods only re-route you if the delay is longer than the newly proposed route?

Personally I would not use the auto reroute feature. The problem with it is if a motorway is blocked, it will most likely re-route you along side roads to pass around the blockage. The side roads will probably not be monitored for traffic flow and with much of the traffic now travelling down these roads, there could be delays here that TomTom knows nothing about.
