The feedback is very useful to hear, and I don't think you are impatient at all!
If you go back and look at the onsets of your Tesla charges, you should see that little spike prior to the charge. The little spike is your Tesla drawing electricity, usually prior to the onset of charge. It's actually quite a bit of wattage, but is short duration and will appear less significant next to the EV's main charge.
Are you getting a lot of incorrect notifications that your Tesla is using power when it is not?
