Please do. Also, how do you calculate the timing between sufficient and excessive carbonation? (I doubt I'm alone in stating that the missus would prefer a sweeter finish than possible without back-sweetening and pasteurizing.)
For a sweeter cider, you would need to check the gravity with a hydrometer and pasteurise when the gravity is higher - like 1010 - 1030 depending on how sweet you want it.
Be careful bottling at these gravities though, if they aren't pasteurised, they will explode for sure.
Stopping primary at this gravity will leave a lot of yeast in solution though. If you ferment dry then backsweeten with a concentrate to bring the sweetness to your taste, then pasteurise, your cider will clear a lot better.
If you can, putting the whole fermenter in a fridge for a couple of days will assist clearing as will transferring to a bottling bucket before bottling.
To determine the correct carbonation for sweet ciders (still a bit of guesswork), fill a couple of plastic 600mL soft drink bottles when you bottle the others. When they are hard, ie can't be squeezed in, they are carbed. This can happen pretty quick so you have to keep an eye on them and be ready to pasteurise. By that I mean the bottle may not be hard for days then be ready over night.
Pasteurising - I set my dishwasher to the hottest cycle - mine is an intensive wash, states 70 deg C. That cycle runs for 2 hours 15. I'm not sure what temp the inside of the bottles get up to but they are too hot to touch for up to half an hour after the cycle finishes. To kill the yeast and stop fermentation, 70 deg for 10 minutes would be plenty (temp of cider inside bottle). Can be achieved at lower temps for longer periods, hence I run the long hot cycle.
I bottle my ciders into 500mL bottles and fit 25L in my dishwasher no probs and pasteurise the whole batch in one cycle.
I'm sure there is info I've left out or do differently to others, but this works for me...
