If you're under pressure to get your c70 inspected, then check your state's inspection regulations . In my state (NC) inspectors are required to inspect any '96-2000 model vehicle with two monitors not ready and any 2001 and later vehicle with one monitor not ready. They cannot fail you in NC because a monitor is not ready or because two monitors are not ready in an older vehicle. Know the rules, and if necessary make it clear at the inspection station that you know the rules and won't take any #$%@ off of them. I made them inspect and pass my '96 Saab 9000 with the catalytic monitor not ready. The monitor finally ran weeks later during a 600 mile road trip...

You don't have any way of knowing whether the flywheel adaptation is complete unless you have a Volvo System Tester or another tool with similar capabilities. I didn't know. I just assumed that since the car's computer should be capable of making thousands of calculations per second, then surely 8 decelerations will be plenty for it to adapt. 8 was probably overkill.

Yes, you can have stop/idle episodes during the 35 MPH runs. It happened to me. I didn't count them as part of the 5 minutes. The purpose of the 35 mph driving is to simulate urban driving conditions. The thing to remember is that when you accelerate after a red light or stop sign, give it no more gas than you need to maintain 35 mph. Pull away from that stop sign or red light with very little throttle input. In my city that is rude and unexpected behavior that can get you rear ended, which is why I did this driving late at night or predawn.
