I didnt read the chart but its basically a bit lower more flour usually and I found I CAN NOT use butter in those chocolite chip cookies as it just pancakes them out.. if you use butter flavored shortening better luck at softer cookies. I moved from sea level to high altitude three yrs ago. My neighbor has been showing me what she does as to her having lived here all her life she doesnt get the difference. It has taken me forever same with baking a potato and roasting a chicken I had to relearn it all! good luck with your cookies but mostly its going to be hit or miss and maybe your new oven is a bit different too in reads so make sure you have another way to test the temperature in there another gage so you can find what it really is running at.
