Spot on with that. You can get the surge by pressing starter like MT did or (and what Shorai suggests) is turn the bike on with the headlight on for that same 10-15 seconds. Just enough to get the juices flowing.
Their design changes for this next round will be reducing the impact temperature has on the battery which will mean less time and in colder temps than you now experience.
Now we just need mid-april to roll around so we can get some reports back on the new version..
