my life is a bit simple because i have only one bike so only one chain. actually, two chains: one on the bike and the other at the bottom of a frozen solid chunk of wax in my crock pot. while heating up the chain i am cleaning the one on the bike, once clean a quick chain swap, crock pot off until the next wax session, plenty of time during the cool down phase to get all that waxy goodness where it needs to be. also only use pure gulf wax, no additives.
never had shifting problems and i do not wipe down after pulling out of the hot wax. i never measure temp and i certainly get way more than one or two rides out of a waxed chain. probably on the order of 400 miles or so.
waxing is certainly more work than just adding some wet or dry lube but i don't mind it and i like the cleanliness and no more tatts. i find i really don't need to clean the chain between waxing sessions since i don't ride in crappy weather and only on solid tarmac.
