Correct me if I'm wrong (as if you guys wouldn't ), but I don't think autostart is basic on the A320 (perhaps it is on the more recent production).
You're wrong. The FADEC will catch any problems and dry motor the engine if necessary.
I don't bother with timing start up as I know I can do an attempted start; an auto-crank; and a second manual start within the time limits. If it doesn't start after that I want to know why and the subsequent return to stand for engineering input will more than suffice for cooling time. :-)
