This is correct.  Technically, I think you are allowed to drive into the control one minute early and request the next minute, but this does not occur very often.  A good rule of thumb is if you always check in on your exact minute, you will always be on time.

One other exception to this rule, though: if your stage time is slower than the bogey time, then you round your stage time down to the minute and use that instead of the bogey time to calculate your time in to the next control.

For example:
Start time: 10:01
Bogey time: 14 minutes
Actual time: 16:35
Transit: 20 minutes
Time in at next control: 10:37 (16+20 = 36 minutes for stage and transit, not 34)

The purpose of this is to ensure that you always have the full amount of time to complete the transit, so that speeding won't be necessary.

It depends.  If it's a Main Time Control (MTC), which are usually only at the end of a leg, you can check in anytime before your correct minute and request a later time.  Normally, though, you must check in on the exact minute.

The route book will tell you if the service is using a normal control or an MTC.  If you're not sure, play it safe - assume that it's NOT a main time control.

This doesn't have to do with timing calculations, but keep in mind that if there is a delay or an obstruction that will prevent you from driving into the control on your correct minute, it is your responsibility to get out of the car, walk into the control, and request your minute from the marshal.

I don't know if there will be a stage rally co-driver's course anytime soon, but it might be worthwhile taking the RSO navigational rally school in March/April.  A lot of the info should be useful and applicable to performance rallying, and you'll learn how to become a top-notch navigational rallyist too!

Oops!  My mistake Tim, it should be 36 minutes.  I've corrected my original post.
