My container is 3 inches across. I got a full melt pool at the 3rd hour mark. I know Ive read that a good rule of thumb is 1inch for every hour, so based on that I think I'm okay. However I remember also reading somewhere that if you get a fmp on the first burn, then you are burning too hot or fast. Should I try wicking down? Other than that, everything else is okay, ht is good, no real shrooming etc.
