MSW is primarily interested in low friction, not chain life. A lot of hot paraffin users add paraffin oil to their wax, in relatively high quantities and still report good results. I think it's smarter to add a much smaller percentage of oil with EP additives to enhance chain life.
My experience so far is a small percentage of oil produces good chain life, but I also apply at 100-150 mile intervals. Using a chain until is squeaks means you waited too long.
I don't ride in extreme cold, but I do ride in the winter and had no problem with wax lube. Truth be known, most of it falls off quickly. There is no way that wax will remain adhered to the high pressure contacts points within a chain, for even a single ride.
I won't have any chain life report until late next year. I've been using the wax lube since last July, but switched both of my bikes over to 12 speed this July and I'm alternating the use of 4 chains on two bikes.
