Based on #329 and #314, it seems that the most recent versions of the PUF and CPS both have the nu06 variable. However, Tax-Calculator does not recognize nu06 as a valid Records variable (see records_variables.json) because the newest versions of the PUF and CPS have not yet been disseminated.
I wanted to open this issue to continue the conversation in #329 and come up with a plan to bring Tax-Calculator up to speed with Tax-Data.
