Maybe faster for at least a rough pass, if you get some help with the
time series stuff ;)

I'll also be helping out with this most likely in the coming months,
as it looks like I'll be doing time series specific coursework.

Very much agree with this.  There are more than few projects that
could be good for interested students as far as stats and statistical
