Look at this recent post from @gchart. Look specifically at the first graph. Whether he starts on turbo, changes the temperature settings or starts on the level 6 or 5 of the stepped ramping mode, at roughly the two minute mark the sustained output is all the same. The point is, just start at level 5 of the stepped ramping mode and don’t create a whole lot of heat at the beginning for nothing. You’re using up battery power and creating heat for nothing.
