Big thanks Diddymal for chicane tip - I'll try it now.

For Elite Campaign Legend I'm just stuck on Chenghou and Sebenco - it's quite distressing to read that people are managing them on 5 attempts - I reckon I've tried more than 500 times!! (and now have a blister on my thumb )

No trouble at all with time trials or speed laps - just the races. Not giving up though, and hopefully with all this helpful advice it won't take another 500 attempts to do it.
