I mean, if it worked as I described below (by "parameter" I meant "set", forgive my French ;), would you grumpy vorts (Stephen, Terry and Jed) effectively opt out from V2G (while retaining G2V of course) by setting the "stop selling" percentage of full charge to 100%, or what would be your average setting? (there must be days when you know for sure you won't be driving a lot, or even not using your car at all)
And what percentage do you think people would set on average? (I myself think my average would be around 80%) Opinions from others welcome too of course.
