I suggest using a half circle or a back and forth motion instead of a full circle, with the flame staying on the close side of the centerline. When I tested the Lotus using my vaping machine ( sucks vapor through the stem), I could see a hot spot under the far side of the indented circle, where the flame has to go uphill, if that makes sense.Just a suggestion. I think you should circle the center of the cap a little more to avoid singeing the goods. You did it a little more in the second hit than the first.
Keeping the tip of the flame too stationary creates a little too much heat in my bowl. YMMV
