That is strange. But you are running it hot. I try to keep resistance 1.5-2.5 but guess your Reo is a mech. Still not sure about running cotton that hot.
I have seen cotton burn at 1.4, my friend did it. Twice. She isn't much of a squonker. I have to squonk mine almost every hit, but I am using a 20/80 sweetened, caramel, vanilla, peanut butte,r graham cracker and tobacco

It is thick, dark and yummy, but it sure eats cotton.
