First meal on the Egg

I followed the advice of many with Wise gurus on this forum and started with hamburgers.
It's hamburger from grass fed beef so it doesn't have as much fat as most hamburgers.
Only had my Maverick so I used the probe on an average size hamburger and cooked to medium. Thermo pen has not arrived yet.
Used cherry wood chips. Maybe could've used more but again following advice and erred on perhaps a little less than too much.
According to the maverick the grate temperature ran around a constant 400°. Surprising that it often seemed to be hotter than the dome temperature Which seem to be contrary to most of what I have read so far.
Family like them and wife even had a second which never happens So I guess it was a successful start. Thanks again for a lot of the advice which helped me get through this first night . I think what's up store for round two will be a chicken of some kind --haven't decided which kind yet
