Updating the R=3.1 values to include WISE bands. Data from Jim Davenport et al. 2014, MNRAS, 440, 3430 (arXiv:1403.1875). Theirs is an empirical calibration, they don't do W4, noting "Due to the small number of systems with good W4 photometry in this matched sample, we were not able to provide robust measurements of the extinction in the W4 band."
That seems to be a theme; it seems noone has done W4 yet. Given that we have only two targets with any W4 data, and they have photometry uncertainties an OOM larger than any other WISE band (~0.3 mags), I think it makes sense to run with these.
