I like to turn it on empty, always enjoy watching the coil heat up and confirms that she is working on all cylinders. But as soon as see a bit of glow (usually within 5 seconds or so) I start tapping in my bud, pop the top on and walk outside by then she has been warming for about 30 seconds or so and I can start on step 2, or I can leave it another 30 till I start to feel a little heat at the set screws and can jump straight into step 3. There is no danger of burnt fingers loading this way as the thermal insulation of the core keeps all that heat were it is supposed to be that early on, be a different situation if I left it for a minute before I touched it though...
