In all seriousness, can I?Throw away that chart and use the proper values from the NEC.

Did you happen to see the note that I posted from that chart in post #15? The values in this chart are no help for what you're asking. When derating a 90° C, #12 conductor you use the ampacity of the 30 amps in the NEC Article 310, T310.16.In all seriousness, can I?
I'd leave it and sleep well tonight.Would you leave the installation I mentioned earlier, or rip it out?
IThe cable gets sleeved into the EMT and then enters into the box. I believe that a minimum of 1/4" of jacket is required in the box. Not being allowed to remove the jacket is stupid but unless the conductors are marked you're not supposed to remove it.
