Hey guys I have a doubt, I probably asked before:

I have been resting my new pan and the only way I can preheat it to the leidenfrost effect is if I use the number 9 (potency goes del 1-9) if I use 5 7 or even 8 10+ might go on and it won't reach that effect. I can sear fried eggs etc without Reachinf it but I was wondering if I might hurth the pan preheating it at 9 and it rKes like five minutes to reach the 200 degrees. I any input? Thanks
