Scheduled departure charge to 100% when off peak ends 00:30am?

[bangtidy]

If I set the car to charge to 100% by 9am and I've told the car that my 4hr cheap rate ends at 00:30am (Octopus Go Faster) am I right in thinking that the car is 'intelligent' enough to only charge to say 90% (or some other value) during the cheap rate time and then do the last 10% top-up just prior to departing?

Or will it just attempt to charge to 100% during the peak rate and then sit there at 100% from 00:30am until we leave at 9am.

I have a Tesla charge so the car is in control of the charging.

Thanks for any pointers!
