Thanks Imc! I did try adding the FO at higher temps and got a nice HT on very few. Am finding that mine is working best at lower temps. That's why I've been doing the variables of 5 to test, it's not always exact sometimes I'm a couple off. But I am finding that there can be a big dif in HT when I compare 160 to 165. Not every FO but so far a few. I am also finding that my temps for adding oils is all over the place, like one works best at 170, the other at 165, another at 160 and another at 150. I could understand if they were in similar groups like bakery, citrus, spice, whatever.... so is that normal, every FO has it's own perfect lil temp? When I first started researching I just assumed each wax in what ever region, combined with house temps and if I'm wearing lucky pjs or not, would have it's own standard temp except for certain groups. I don't mind doing so many temps on one FO, it is time consuming but I am only doing 1 oz per temp. But the burning through it all is taking a long time LMAO, who knows maybe I am crazy and there is no dif at all Thanks again!
